1 Highlights Our team has worked hard to advance the SynerGEE model and build new and useful engineering applications for this update.

• Model improvements and new applications for simulating and analyzing systems with PV. The applications evaluate performance and hosting capacity.

• You can now place raw irradiance or kW output data into a spreadsheet to drive SynerGEE Electrics Time-Series analysis. That analysis can be run down to 1 second intervals for a full 24 hour day (nearly 90,000 time points)

• More time-dependent applications have been built for load modeling and switching.

• We have extended our secondary models and you can now run secondary loss analysis

• Many new model updates and editor improvements

• Better charting

• New tool for exporting and importing data

You can read more about these updates and many more in the pages that follow. We appreciate the time and insight that so many of our clients have shared with us. We hope that you find many useful improvements in this release. Please let us know about problems that you might see, improvements to make, or ideas that you have for new development. Thank you, The SynerGEE Electric Team

8 Analysis

2 Analysis

2.1 Time Series Analysis This new application in SynerGEE Electric is capable of analyzing the behavior and performance of the distribution system model down to 1-second intervals. This type of analysis is crucial for understanding the impacts of PV saturation on the model. Here is the output of a large PV station modeled in SynerGEE Electric 5.1:

The analysis performs sequential load-flow analysis and calculates transitions in state for various facilities like generators, batteries, or switches. It is not a dynamic analysis because it is not integrating the response of equipment that might be represented with differential equations. Dynamic analysis is used for power system stability studies or other studies dealing with the transient nature of rotating machines or solid-state devices. Our application moves a model linearly from one time point to another. The goal of the application is to give you a tool to analyze your model’s behavior with PV, switching, batteries, and changing customer demands. An industry term is ‘quasi-steady state analysis’. That is a fine term. We are a little more ‘meat and potatoes’ oriented and prefer time series analysis as a name.

The new application can be found on the Analysis ribbon:

The application has a number of settings groups.

Analysis 9

There are two key options for running the analysis:

• Run the analysis using data from an external spreadsheet

• Run the analysis with no external data. The SynerGEE weather modeling and cloud modeling features might drive the volatility of the model.

It can potentially run over a single day. However, you can and should set the starting and ending hour for the analysis. The application generates a lot of results and it is best to focus on useful times for running it.

If you have recorded irradiance data for your PV models then you can store the data in Excel and tie it to generators in the model. Here is a graph of raw irradiance data in Excel:

10 Analysis

The left-most column of the Excel data file needs to be populated with simulation seconds.

The interval between time points does not need to be regular. Time intervals can be skipped. However, SynerGEE’s time range analysis generates most of its output in chart form. More regular time intervals will result in better charts.

Remaining columns in the spreadsheet will either need to list input or output codes. The heading of the column must be made of a three-part text:

Code, ID, User description

An example is:

IN_GEN_KW, 22393, Barker St. NG unit

This spreadsheet column heading indicates that the column contains kW output values for the generator on section “22393”.

The following input codes are supported in this release:

Code Description

IN_WTZ_IRRAD Column lists irradiance values in W/M^2 for the particular weather zone. Any generators tied to the specified weather zone will be driven with the irradiance values.

IN_GEN_KW Generator instance kW is specified in the column.

IN_SRC_VOLTS Feeder or substation voltage is specified. Values are in volts.

These outputs are supported:

14 Analysis

We are very excited about this new and very powerful engineering application. Please let us know what you think and if you have ideas for input and output that would make it even more useful to your utility.

2.2 PV Analysis PV Analysis is a new application that is designed to help the engineer evaluate growing levels of PV saturation on feeders or substations. “How much PV can I add to a feeder?” is the question that the application is designed to help answer.

The application applies PV generation to any section in the model with distributed load. It grows the generation over 10 steps to the limit specified by the user. Loading levels, maximum loading, and min / max voltages are reported. The engineer can look at the plots and determine what level of saturation is generally acceptable.

Here are the settings for the application:

Here are some generated plots:

16 Analysis

The user picks the maximum saturation and the range of hours to evaluate. The hours from 11 – 4 might be good ones. The saturation level is determined for each hour based on the loading level. The calculations for each hour are independent. The min, max, and average are from the results for all hours.

2.3 Screener (323) This new application will run over an hour time range over a range of months. Load-flow results are gathered for this hour-by-hour analysis.

The settings for this application allow you to bring up the time range settings and the model ratings settings:

Settings in these common editors are used to drive the analysis.

Once run, the screener generates a report showing violations and the number of hours that violations were sustained over the specified time range:

The application uses the range of months specified in single-year analysis and finds time points where there are loading or voltage violations. The number of hours where violations occur are listed along with the overall min or max value.

Ideally, engineers will run this analysis and see the report come up clean.

Here are details:

We will add features and exception checks to this application in coming release. If you have issues that should be ‘screened for’ in your feeders, please let us know.

2.4 Single-day analysis (288) We have built a new application to run over a 24-hour period of a single day. It will use the day that you have setup in the model time-of-day settings. This new application adds to a series of time range applications on the ‘Planning’ ribbon:

The application produces charts like this one showing substation demand over a 24-hour period:

2.5 Time dependent switching (61) New application called Time Dependent Switching will run switch plans over the user specified time interval on the selected day.

A resulting report will show min volts, max volts, max loading, reserve amps, etc. for each plan and each hour. The engineer can look over the report to find switching hours that might be problematic.

2.6 Time range settings (392) Many applications in SynerGEE analyze the model over a time range. We have consolidated that time range setting to the ‘Time & Weather’ model settings editor:

Slide the controls up and down to select the month and hour range for analysis.

22 Analysis

Note that some applications run over hours on the specified day type and so the month range is not used.

2.7 Show multi-year analysis results in chart reports (342) Multi-year modeling in SynerGEE is ten years old. Until now, results from the multi-year analysis have been densely reported in tabular reports. We added chart based reporting in SynerGEE 5.0 and now we have the means to show the trends of the model over a 10-year period in a graphical format.

There is a new setting on the multi-year analysis settings that switch between the tabular reports and the new chart reports. You can dump values from either report into Excel.

Here are some of the charts:

voltage calculated in load-flow analysis. We plan to make secondary loss information available in the results tabs and most load-flow based reports. The 5.1 release just shows secondary kW losses:

The new application is on the ‘Planning’ ribbon. Our next steps are to estimate customer voltage range and issue summary metrics for the various types of distribution transformers in a model.

2.9 Min / Max Z Analysis (143) A new application on the ‘Protection’ ribbon will run fault analysis on your model with minimum and then with maximum source impedances.

A report lists fault levels at minimum and maximum source impedance along with the percent difference between the two:

You can also color the map by percent difference for each type of fault:

26 Analysis

2.10 Allocate distributed generation (365, 116, 318) The need to consider the impact of distributed photovoltaic generation is growing. Most of our clients have some level of need for studying residential PV. However, very few of our clients have data that can be accessed and used to setup PV generation on their models.

For many clients, questions about operating today with PV generation are not critical. The important question is, “How much PV can we support on our various feeders and subs?” Distributed generation levels on meters and many other features in SynerGEE Electric 5.1 are designed to help you answer that question.

If you have some idea about the level of distributed PV generation supplied for a feeder or if you are simply speculating about potential levels, you can now use load allocation in SynerGEE to setup distributed generation. This new feature will enable you to spread section distributed generation values downstream from meters.

Since a small number of our clients are actively dealing with PV modeling, this is an important feature. It will allow all of our clients to get up and running with PV. In just a few minutes, they could be running PV studies on their feeders even though they have no solid data for PV installations.

Multi-year enabled and by-phase distributed generation kW and pf values have been added to meters.

Analysis 27

You can now enter DG levels for the section DG downstream from a meter. Allocation will setup section DG in proportion to the c.kVA on the section. Cascading meters can be used and the nearest meter should hold levels for everything downstream. A meter will only allocate DG on the sections between it and the next downstream meter setup for DG.

Activate DG allocation in the load allocation settings:

Sections fed by a DG configured meter and having distributed loads will have distributed generation values added.

28 Analysis

2.11 Allocation demand slider snaps to Nominal (317) A feature exists in load allocation to allow you to quickly ramp up or down the overall demands being allocated.

Meter demands have a scaling range. The default is from 75% to 150% scaling and you can change the intervals to be tighter or broader on a meter-by-meter basis:

Then, when you run load allocation, you can scale the demands on the meters.

Page 29: SynerGEE ReleaseNotes

Analysis 29

If you set the scale to the ‘Max’ level then each meter’s demands will be multiplied by the upper scaling range. Some meters might use the 150% default while others have upper limits of 125% or even 100%. This system allows you to grow loads in areas that might have the propensity for demand growth.

We fixed a problem in SynerGEE Electric 5.1 to snap the slider on the allocation settings to ‘Nominal’ when it is drug close to that area. Previously, a slight offset of the slider (as shown above) would result in unexpected allocation results.

3.5 Advancement of distribution transformer model (314) Our goal is to have a general and reliable engineering representation of distribution transformers in your model. It is not to model each distribution transformer or to place data burdens on your model related to distribution transformer inventory (which could number in the millions for many of our clients). Distribution transformers need to be represented in the model to:

• Account for losses

• Identify potential overloading or under loading

• Identify potential under voltage problems

• Identify potential over voltage problems (possibly due to PV)

Distribution transformer instances, database tables, and a tab within the section editor was introduced several versions ago in the SynerGEE model. We are expanding the distribution transformer with more data that we can use for loss and voltage analysis. This analysis is not in place yet … but we are working on it. For now, the information can be informative. We have also added tools in this version of SynerGEE to see distribution transformers on the map and to collect sum their data and apply it to the section distributed load model.

Here is the distribution transformer tab on the section editor showing all of the transformers attached to the section:

We have added new parameters to the model:

• Transformer type and connection details

• Service line conductor and length

• Customer zone

• More demand details

The service model is in place to allow the calculation of secondary voltage and estimation of distribution transformer losses. Losses will be associated with the transformer, of course. Transformer types can now be marked as ‘center tapped’ and we will be able to deal with that parameter when we get to the loss calculations. Service cable will play a role in voltage drop estimates.

You can see that we have extended the demand portion of the transformer record. There are actual kW values as well as connected values for energy, customers, and generation.

We plan to incorporate the reporting of distribution transformer calculations in the various time of day analysis. One outcome would be the identification of potential high voltages on customers with PV and light daily loads.

The Raw data group contains information that was coming directly from CMM.

We will be extending CMM in upcoming releases to deal with our more detailed distribution transformer model. Values in this group hold information coming from CMM today.

3.6 Battery model Generators have been extended with a battery model. In the model, batteries provide a constant kW output within the boundaries of their stored energy and minimum discharge levels. A generator is set as a ‘Battery’ type in the warehouse:

A battery has the following additional ratings:

• Energy – capacity of the battery in kWHr

• Efficiency – discharge and charge efficiency

Select the battery type in a generator instance:

Then, you can set the mode and rates for charging and discharging:

The minimum discharge level sets the bottom threshold of energy storage. A 4 MWHr battery with a 50% minimum discharge has an effective 2 MWHr of usable capacity.

Here is a listing of the various modes for the battery:

Mode Details

Discharge Battery will look like a constant power generator. It will discharge continuously. Energy limits are not used in this mode. The power level is based on the discharge rate.

Charge Battery will look like a constant power load. It will charge continuously despite the energy limits in the warehouse type. The load power is based on the charge rate.

Time dispatched The battery will follow the hour-based schedule. It will begin charging and discharging after the specified hours. It will charge or discharge until reaching 100% or the minimum threshold of its energy level. The power level is based on the discharge and charge rates above.

Load following The battery will charge if its energy level is below 100% and the downstream kW load is below the ‘Charge’ setting. The battery will discharge if the downstream load is above the ‘Discharge’ setting. The power level is based on the discharge and charge rates above.

Ramp rate reduction

This is similar to the Load following mode except that charging and discharging is based on the slope of the downstream load in kW/sec. This mode should be used with time series analysis.

3.7 STATCOM models (267, 145) We now have a steady state representation of the static compensator (STATCOM) device.

This power electronic device is commonly used in transmission and generation – particularly wind generation. Its strength is a fast dynamic response to voltage changes and the consumption or injection of vars. In the steady state, we are modeling the device with a set point, ramp rate, and var limits.

STATCOMs need something to generate a DC voltage. This is typically a generator or power electronic supply. We are putting the STATCOM into our capacitor model because it is a var generating or var consuming device. STATCOMS do not typically use capacitors. That allows them to be small, and light, and cheap.

You can activate it on the front tab of the capacitor.

We also did some aesthetic work on the cap editor:

Here is the performance of a 1200 kvar cap against a +/- 1200 kvar STATCOM set at 122V. The voltage was varied from 119V to 125V. The STATCOM is bold and in blue:

You can see how it generates vars when the voltage is low and consumes vars when the voltage is high. Here is how amp load compares:

This is a case where a dynamic analysis would be much simpler. Getting these devices to settle down during load-flow is tough.

3.8 Use transformer high side ratings for unrated subs (62) Feeders and substations that are missing ratings will use the fed meter, transformer, or first line conductor. If the transformer is the first facility outside of the sub then it will be used. When transformers were used, the secondary amp rating was applied which gave subs enormous capacity. Now, the transformer windings are used to get the high side ratings that are then applied to the sub. Again, this only applies to cases where sub or feeder ratings are zero. If the user sets rated values then those rated values will be used.

If your substations have specified ratings this this issue does not apply. Here are amp ratings in the subtran editor:

But, if these values are zero, SynerGEE will use a rating based on the next downstream transformer, meter, or conductor:

The transformer will be used in this case. The substation amp rating will be based on the high side amp rating of the primary transformer. When load-flow is run, we can now review the percent loading value for the subtran:

3.9 Limit use of generator type to instance types (152) The check boxes for the use of generators for sections, large customers, or generator instances have been replaced by radio buttons.

This means that a generator type can only be used for one type of instance. We are going to use this new approach to eliminate the need for voltage ratings on section generators. There is a new database field for the new field. The three old Boolean values are still in the schema and will be removed in a future release.

3.10 Section distributed generators no longer need type (364) Modeling residential PV on sections is becoming more important. PV output is driven by model settings, time of day, and/or irradiance profiles. It is now not necessary to specify a generator type on the section instance.

Here is a section setup with 2.3kW of generation. The output is set to 80% of that level:

3.12 Center tap field added to transformers (317) There is a new field to indicate that a distribution has a secondary center tap. This new field is not yet used in analysis.

We are planning to estimate secondary losses and secondary voltage in upcoming releases. We added the data field now in preparation.

3.13 Weather zones (260) A weather zone is a set of monthly profiles for:

• Irradiance

• Wind speed

• Temperature

• Humidity

These profiles are used to drive renewable generator models like PV or windmills. The profiles can also be used to affect customer load models or even line impedances.

Weather zones also have a set of factors used by a cloud modeling system in SynerGEE. This system can be put to use in PV modeling if actual irradiance readings are not available or conducive to the type of stress analysis being performed.

Weather is likely consistent for substations over large parts of your distribution system. However, terrain and geography can have an impact. You may also have a distribution system covering a massive area. A small mountain, for example, might warrant the use of two weather zones. Weather zones can be setup and swapped in and out of feeders to evaluate different conditions.

Weather zones are applied to sections weather model so that analysis can be run over a full day at intervals down to 1s. Simplify the cloud model. Allow cloud-free operation during early and late hours.

Here is a screenshot from a run over an April weekday:

Weather zone settings were configured so that variation in irradiance only occurred above a particular threshold.

3.14 Corrected potential problem with reserve amps(408) The reserve capacity can also be thought of as the pickup capacity. The value indicates the demand that can be added to a section or facility without creating an upstream overload. In the system below, we would like to know the reserve amps at point ‘A’:

The demand current, or reserve amps, that can be added to point ‘A’ is the current that will not cause an overload at ‘W’, ‘X’, ‘Y’, or ‘F’. Continuous and emergency settings are evaluated independently. Thus, continuous reserve amp and emergency reserve amp values are calculated based on continuous and emergency ratings respectively.

A problem was found with this scenario:

We calculate reserve rating using the amps out of facilities. The first section of 1/0 has a large load that should create a reserve amp bottleneck of at least 60% loading since 1/0 is only rated at 212 amps.

( )100 25% 100%

212Reserve

Exception Limit Derating Factor+

= ⋅⋅

Because we were evaluating reserve amps based on the current out of the section, only the 25A demand was being used to determine reserve limits. The 100A load was never included in the reserve amp calculations.

Now, we will evaluate the value of amps into and out of sections when calculating reserve amp limits.

3.15 Potential for bad feeder assignments for unfed sections (222) There are many challenges to making feeder assignments for sections in multi-year models with switching-by-year. We set the model into the base year before saving and making the feeder assignments. We also try to make a logical feeder assignment for unfed sections based on proximity, open switches, etc. Inactive sections are sections that are unfed in the base year but could be fed in future years through multi-year switching. We have to distinguish between unfed facilities and inactive facilities to try to make feeder assignments that make sense.

We have worked on an issue that we were seeing due to loops being present in the base year model when multi-year facilities are flattened into it. When there are loops, the feederID assignment is arbitrary among the set of feeders feeding into the loop. We have made some changes in the process used to establish the owner feeder during the save. It should be more robust and correct the potential problems.

Also, these fields have been in the table and are now being populated for switches:

The dialog that the backup reminder uses is the same dialog that our message boxes are using. It is a standard Windows dialog with many extra capabilities that allow us to add useful buttons and check boxes. The new ‘backup’ dialog should work like the old one did (204). Finally, we continue an ongoing effort to get our editors and general user interface items more in line with Microsoft’s standard. This mostly involves things like use of capitalization and quotes, so functionality will not change with this work (205).

4.9 Year selection tool is easier to use (248) We implemented updates to make the year selection tool more intuitive and easier to use. The year for analysis is shown above the explorer and is important for looking at planning issues in future years.

First, the little up and down arrows will be grayed or disabled when the mouse is not over them. When you bring the mouse near them, they activate and can be used to increment the year for analysis.

Next, years beyond the base year will be shown in a blue color:

Finally, a context click anywhere in the zone at the top of the explorer around the year should result in the year context menu appearing:

You can choose any year directly from this menu.

4.10 New settings management system (228) The number of settings for SynerGEE Electric has grown to thousands. We set out to add capabilities to SynerGEE Electric 5.1 to help your team manage the settings and to make it easier for you to capture the settings for a single application, like Contingency or Fault Analysis. To do this, we consolidated settings into XML files and developed a management tool.

These new settings file are kept in the ‘Settings’ folder and they have an XML extension:

Nearly all settings can now be stored in a single XML file. Furthermore, settings for particular applications can be saved into a stand-alone XML fail and loaded or merged into a SynerGEE Electric session.

Access the settings manager with the properties button on the upper-left side of the window:

Bob's settings

Fault settings

The settings manager has a panel listing all settings file found in the ‘Settings’ folder. The tree on the right side of the manager shows the categories of settings stored in the selected settings file:

Default settings are loaded when SynerGEE Electric starts. That is the settings XML file that is selected when you open the settings manager.

You can save all of your current settings by typing a name for the settings file and pressing ‘Save’.

You can save just the settings for an application like contingency analysis with the same approach. First, however, uncheck all of the roots in the settings contents tree:

Next, open the ‘Applications’ root and check the ‘Contingency’ item:

There are also many freely available tools for comparing XML files. They will search the over 3500 tags in the settings file and identify differences like this:

We could certainly build editors and comparison tools in SynerGEE Electric. However, there is a rich supply of cost free tools to work with XML files. We will likely put our efforts into building tools more beneficial to your engineering analysis needs.

We are listening, though. Let us know what you think about this very flexible and powerful settings management system.

4.11 Password encryption in XML files (224) Passwords in the SynDataSources.xml file will be encrypted now. The encryption key will be stored in the xml file as well and will be used for all passwords in that file so that users can share data source collections if necessary. As an example, a password might start as “JPSModel14092010”. This will be encrypted as something like “5þ¯¬¥_[zTê�ñ¹” and then encoded as “GTX+rx+lX1t6VOqdGfG5Gw==” (to avoid any invalid characters for the xml) which is what will be written to the xml file.

4.12 Defensive startup options (144) On rare occasions, SynerGEE has trouble starting up. It is difficult for our clients and our support team to determine if the problem is related to the computer environment, the network, the model, or the SynerGEE install. Features were added to help SynerGEE startup when it fails under normal conditions.

• We added some code to SynerGEE’s startup procedure that should catch catastrophic errors more gracefully and inform the user of the general area where they occurred.

This information will not help the user very much but it could help us determine the cause of a crash. If you get a crash at startup, please phone or e-mail us with this new information.

• Added “-b” as a command line option. This will start SynerGEE with no map in order to give the user a way to at least start SynerGEE and work from there to help us determine the cause of their crash.

• Added a new executable named “EnvironmentManager.exe”. This can verify the various paths that SynerGEE uses (output, macros, etc.) and can also clear the registry settings and the startup script. This will be an effective tool to help clients who are suddenly experiencing startup crashes.

Again, crashes at startup are very rare but when they do occur, they are difficult and frustrating to correct. Hopefully, these new features help out in this situation.

4.13 Allow loop creation defaults to ‘Yes’ (312) SynerGEE will not allow loops to be created with the reconnect tool or switching when the ‘Allow Loop Creation’ option is set to false in the properties. This is a useful feature if you feel that analysis on a model with loops would not be consistent with the operating practices of your company.

We find that engineers are more and more likely to need to close in loops and run analysis. We have made the default settings for this option “Yes, allow loop creation”.

Nearly all applications run with or without loops. You can create a loop through switching or reconnecting and SynerGEE handles the rest. You do not need to do anything special for analysis runs.

Remember that you can easily identify loops (or wandering laterals) in you model using the Color By Path Type mode in the display options:

5.1 Warehouse comparison report (316) The model compare tool is very useful. It compares facilities in your model in memory to a database. Comparisons are made table-by-table and field-by-field to show additions, deletions, and modifications. The resulting report can be used to capture changes in your model.

With this SynerGEE Electric release, the compare tool has been extended to cover the warehouse. Your company should have a goal to manage a limited number of shared warehouse databases. If warehouses need to be consolidated, you can use the new Warehouse compare tool to find the differences and types that may be in one database but not the other.

Once you have done a review, the best way to consolidate is to take the best warehouse, load it into SynerGEE, and then load other Warehouse databases. The 'master' warehouse database will be the one in memory. Items in memory are always kept when a conflicting item is found in the database being loaded.

Once the databases are combined, you may need to use the report from the Warehouse comparison tool to identify field level differences and make corrections.

The summary table shows the total number of differences between the warehouse in memory and the one on disk in a database:

Here are some of the field level differences:

7.6 Distribution transformer processing (57) We are advancing the modeling and analysis of distribution transformers with each SynerGEE Electric update. We have made many modeling updates in this release. We have also added a new application for processing distribution transformers.

The application will do one of three things:

• Generate a report comparing totals from DTrans to values for the respective distributed loads. C.kVA, #cust, etc are compared by feeder.

• Sum up distribution transformer values and assign them to the section distributed load.

• Generate distribution transformers to approximate the total distributed load on a section

The last option is primarily for our testing but it can be used by clients to get some idea of how distribution modeling will work on their system and how applications can be leveraged. They might also use the application to generate distribution transformers for a quick estimate of secondary losses or min/max customer voltage.

Here are the three options that can be used with the analysis:

We reworked the contents selection in the data source editor to use our checklist combo box rather than the growing set of check boxes that were there. The list of check boxes is limited based on the data source provider selected on the first page of the wizard.

7.14 Notes field in DSA - Data Source Alias (295) Comments can be added and maintained for DSAs. The comments might reference the model build process, model location, or history of the data source.

8.1 New import / export tool (352-354) We have built an application that will import or export to various modeling formats.

This application allows you to select various formats for data import or export.

Please let us know about common or standard formats that would be beneficial additions to this tool.

When using the tool, you have to supply appropriate paths and settings. Some of the tools generate sample outage event or billing data for your model. One tool exports to a format used by OpenDSS.

8.2 Data Hammer updates (4) The data hammer is a tool to make critical updates to help you get up and running with a model. You can find the tool on the ‘Forge’ tab and use it to set data values. We have added new options to create missing regulator, generator, motor, or transformer types.

When you run the tool with these options, SynerGEE will create a new type in the warehouse for any missing types that are referenced in the model.

8.3 Sample outage data SynerGEE Electric has a new tool to generate sample outage events for your model. This tool can be used to create an outage file that can then be run through the reliability event manager to create sample exposure zones for your model.

This tool should not be used for analysis in a production capacity. Actual events or data developed from the typical events on the system should be used for actual studies. This new tool was added to help engineers investigate the capabilities of SynerGEE Reliability. Collecting reliability data does require time and resources. The sample outage data generated by this tool will help the utility evaluate the use of reliability event data and the value of those efforts.

The new ‘Export / Import’ tool can be found on the Forge ribbon:

When the export / import wizard comes up, fill in the filename for the reliability outage events. There are other paths because on the panel because some of the other systems require multiple files for

imports or exports. You can also specify the number of failures per mile for each year. Outage events will be generated for a 5-year period.

A text file (with an .OutSet extension) will be generated in the Scripts path. Paths are managed in the SynerGEE preferences. Here is the file loaded into a text editor:

The exporter uses 6050 events for outages. You can investigate this record and others with the outage event file schema on the Support ribbon:

A 6050 record corresponds to a section event:

The categories and subcategories of the events are gathered from the ReliCauseMeta.txt file in the Settings folder. These are the same events that would be seen in the exposure zones editor. The export tool generates random events on random sections for a five-year period.

The Outage Events Wizard needs to be used for two things:

1. Move the events from the text file that we just created to a database

2. Process the events in the database to create exposure zones with failure rates calculated from correlated events

A target database for the events is needed. If you have an existing databases in Access, Oracle, SQL Server, MySQL, or Informix, it should be marked for holding event data with the Data Source Manager

The target contents for a data source are specified within that DSA Wizard:

Once a database has been marked to hold event data, you are ready to proceed.

The outage event file can be processed and applied to the model in SynerGEE as exposure zones. First, launch the Outage Events Wizard from the Forge ribbon and choose the ‘Import events in data file(s)…’ option:

Next, select the outage event file and select a target database.

Then you should create a target data set in the database:

A summary page will come up next:

Now the events have been brought into a dataset in the target database. You can use SQL Dashboard in SynerGEE to mine the data. Run through the Reliability Event Wizard again with the second option to create exposure zones and process events:

As you step through this wizard, you will see options to choose the database and data set that we just generated. When the wizard completes its processing, you will have new exposure zones on the model.

You can run through the second process to create exposures zones over and over to setup exposure zones in different ways. The first process that loaded data from the text file only needs to be done once.

8.4 Model Forge / Middle Link Commands • STN_108 will NOT build a default transformer device where SubTran node exists. This

is identical in functionality to existing code 611 in MiddleLink (263).

• MiddleLink record 1602 has been added for the generator actual phase, not the metered phase (272).

• MiddleLink record 512 added for spot load kWh (386).

• MiddleLink record 816 and 905 for breaker and fuse phasing respectively (406).

• New MiddleLink commands for generators (363):

ML 227 - Section Generator is On

ML 228 - Section Generator Description

ML 229 - Section Generator Type

ML 230 - Section Generator Location

ML 231 - Section Generator Specified By-phase kW/PF

• There are new Model Forge and MiddleLink command to handle by-phase kW/PF generator ratings for the Large Customer device. See LGC_121 and ML 1413 respectively (351).

8.5 Solver interface for irradiance and weather profiles (180) There is a new interface available for weather profiles: Solver.Warehouse.WeatherProfiles. Users can add and delete profiles as well as count them by profile type or as a total over all types. The WeatherProfile interface allows editing of a profile’s data and type. There is also a new recipe available (Warehouse.WeatherProfile) to allow adding and editing of profiles.

104 Miscellaneous 5.1 items

9 Miscellaneous 5.1 items • Dock-able reports were showing up on top of the modeless editor after analysis runs.

Now, the editor will remain on top of any emerging reports (149).

• Automatic backups will not be run until right before analysis is run. This is to prevent backups from being run when SynerGEE is busy running other tasks. Backing up the model in the middle of these tasks might have resulted in a crash or an incomplete model save (151).

• SynerGEE monitors scripts and macros folders so that names are updated in various combo boxes or ribbons when you edit, rename, add, or delete a script or macro file in one of these folders (213).

• Added AMS Link to Model Explorer columns for: Breakers, Capacitors, Fuses, Large Customers, Reclosers, Regulators, Sectionalizers, Switches and Transformers (416).

• Undo / redo was not completely refreshing the screen after a node – substation conversion (78).

• Our KML output was causing Google Earth to head to Antarctica instead of the proper location. We needed to switch the order of the coordinates in the KML file (223).

• We were using double quotes instead of single quotes for our query to pull out the lat / long data from the database when generating KML files for Google Earth. Single quotes are better for Oracle (292).

• Sometimes the docked or undocked reports would result in a crash when they were closed. We fixed the problem (246).

• The Rated kW and pf edit boxes in the section’s distributed generation tab will work like they should now. They should be similar to the edit boxes on the large customer’s generation tab. We also fixed the kw / pf total and average edit boxes on the large customer and section editors so that they reflect the active phases. Previously they displayed the same value regardless of which phases were selected (368).

• Dockable reports were not printing correctly in some instances. The problem appears to be related to the way we were hiding the reports while the print view was displayed. They should behave as expected now (273).

• There were several inconsistencies in the printing of reports, both from the dockable and non-dockable reports. The printouts from each should match up now (287).

• There is a new “Delete” option available on the TCC set context menu. We also modified our handling of the TCC context menus so that they work like the context menus on the map and model explorer. The items displayed in the context menus will be relevant to the item that was clicked on (such as edit or add) or relevant to the whole view if no item was clicked on (such as properties or feeder selection) (189).

• During training, we saw a problem where switching resolutions (in this case, using a projector) made the floating legend window go away. We have made some changes that should handle a resolution switch or a change in the number of monitors. To see the problem, launch SynerGEE and put the legend window in the upper right corner of the right-most monitor. Shut down SynerGEE, lower the screen resolution, and restart SynerGEE. The legend window should now appear whereas it was lost before (291).

• The e-mail generated from the first running of SynerGEE Electric will no longer prompt with a dialog about the model and settings (308).

Miscellaneous 5.1 items 105

• Added some extra text to the support email to identify some of the issue details that we may be looking for. The new text only appears in the regular emails, not in the “first time running SynerGEE” emails (286).

• There were some issues with our handling of source nodes in the partial loading process. SynerGEE was locking up. The problem has been corrected (364).

• There were some issues with these generator database fields: DGenDesc, LocationToModelDGens and UseRatedOutput (363).

• Fixed an issue with copying customer classes in the model explorer's warehouse tab (373).

• New Model Forge commands LOA_125 and LOA_126. They work exactly like LOA_123 and LOA_124 except they set load values instead of adding on to them (384).

• We have added a model cleanup script command that will delete all large customers in a model with no load, no generator type and no rated generator kW (360).

• SynerGEE was allowing multiple radio buttons to be selected on the section distribution generation tab (379).

• All sub-reports and charts in the Load-Flow : By Voltage Range report were not handling different user voltage bases correctly. The different base values were being processed twice. We removed the second processing instances so this report should now be able to support any user-defined voltage base (261).

• Updated model schema so placeholders now exist for the three By-Phase checkboxes in the InstTextLabels table (264).

• There were some memory management issues that might have come up during the addition and deletion of points in the TCC curve editor. Things should now work better in general. We also tweaked the status bar message so that it reaches the whole way across the status bar except for the combo box on the right (279).

• Fixed several issues related to the 'star' configuration of motors. The star/delta refers to the factory connection of the motor. Nearly all motors have delta connected windings (366).

• The DSA validation tool was not working in the dockable report window so it will come up in a report window regardless of the report setting. (397)

• Not all tables were being dropped in Oracle when an associated model was being dropped (370).

• Large customer loads will now have a demand that varies hour-by-hour during a single-day analysis or other time series analysis. Previously, the load would just remain unchanged at the analysis hour in model settings (94).

• Metrics in the Screener report that are not violations have blanks in their report cells instead of zero. Only the hours of recurrence of violations are shown in the screener report (382).

• SynerGEE may use one of three different Access drivers when connecting to an Access database. We made some improvements so that SynerGEE is more likely to pick the right driver based on the Access 2007 database file extension (144).

10.1 SynerGEE Electric 5.0.1.343 (13 Jun 2014) • The maximum number of categories in the ‘color by’ system has been increased to

550. This will allow well over 500 feeders to be independently colored on the SynerGEE map (383).

• Internal tie switches on wandering laterals were showing up in arc flash reports. Those switches do not impact results and are no longer listed (149).

• Fault flow analysis was crashing. We fixed a memory overlap issue related to Fault Flow running on models with wandering laterals (259).

• The ‘FeederID’ field on sections may not have been saved correctly for multi-year models with by-year switching changes. Corrections have been made and feeders can be loaded from large databases with multi-year models (222).

• The ‘OwnerFeederId’ and ‘TieFeederId’ fields have been properly configured in the switch database table (222).

• Switching in networks : Previously, only switches could be used for switching network models. Now, breakers, reclosers, and fuses can be used (257).

• SynerGEE sets the model to the base year before saving to a database. Sections and switches set to be energized in future years are temporarily setup in the base year to get a feeder assignment. That feeder assignment is used in the target database when individual feeders are loaded. We corrected a problem with the open / closed status of switches in pre-energize years. SynerGEE was using the open / closed status of the base year during a save for switches set for future year energizing. That resulted in unexpected feeder assignments. Now, SynerGEE will set the open / closed status of switches in the base year to match the status of the switch in the first energized year (244).

• The icons of the devices in the TCC will be displayed in red in the protection tree so that they stand out (245).

• We worked to simplify the time of day settings in SynerGEE 5.0. Unfortunately, we overlooked updating the recipe command used to set time of day in a macro. Command 3233 lets you specify the month, day type (0=we, 1=wd, 2=pd), and the hour as a numerical string. Things should be working now. Hours are specified from 0->23. Midnight is 0 and 23 is the upper limit of a numerically specified hour (4717).

• Distributed generation values on section were not saving correctly in the base year and multiple years. There are now kW and kvar fields in the Inst_DGen tables to capture the base year generation. This generation will be loaded and applied even if MYM is not active (370).

• The Rated kW and pf edit boxes in the section’s distributed generation tab will now work correctly. We also fixed the kw / pf total and average edit boxes on the large customer and section editors so that they reflect the active phases. Previously they displayed the same value regardless of which phases were selected (368).

• We fixed a problem causing the warehouse information in the explorer to disappear (358).

• SynerGEE was allowing two radio buttons to be selected on the section distributed generation tab (379).

• A model building process needed to set load values and not accumulate them. New Model Forge commands LOA_125 and LOA_126. They work exactly like LOA_123 and LOA_124 except they set load values instead of adding on to them (384).

• New Model Forge commands SEC_125 and LGC_122 (360).

• New MiddleLink records 227, 228, 229, 230, and 231. Also fixed DGenDesc, LocationToModelDGens and UseRatedOutput fields that were not linking properly between SynerGEE and the model database (308).

• New Middlelink record 1602 (3).

• New Model Cleanup record 4043 – Eliminate Large Customer w/ no load or generation (306).

• New Model Forge command LGC_121 and new MiddleLink record 1413 (304).
