Dominion – Business Challenge

Get more value out of the OSIsoft investment and the

data we collect.

Start using the data we collect in ways that can help

prevent plant issues and equipment failures.

Share Best Practice information.

Provide data to users in various platforms, i.e. mobile

accessibility.

9


Dominion – Solutions to Challenge

After attending an OSIsoft Conference, an eye opening experience, we formulated some creative ideas.

Management approved 2 FTE’s to support the PI System.

We implemented some low cost OSIsoft partner applications to find out if our customers found value in the data presented.

Began having internal PI User Group meetings.

10


Dominion – Solutions

Alerting – With a robust amount of PI System information available at most of our generating plants, we implemented Topview from Exele.

Started with Unit On/Off line status to Executive, Station Management, and Support Teams.

Grown to all forms of station operational data, providing KPI status.

Delivery thru email, text messaging, and telephony device.

11


PI Manual Logger – Sites were asking for ways to eliminate paper logs, and have more accountability of the data collected.

Invested in Windows Mobile devices, that were now much more manageable in size, and could provide various solution options.

Data collected, becoming part of the PI System database, provides enormous value, that now has become a Power Generation ‘Best Practice’.


12



PI Tuning Tools - The PI-POC’s were provided tools

to help tune the existing PI System tags.

Tuned PI System tags will store data with known

compressions, which will provide more value when

needed.

Data being supplied for other implemented solutions

would require trusted data.

13



EdictVB – A performance calculation

tool that required little VB coding experience.

The ability to perform calculations across the Fleet PI

Servers, and bring back information used for

Executive portal pages.

Extract data from outside data sources, like weather

stations, that could be used with existing PI System

data.

14



Transpara – Data mobility. Web based information delivered to mobile devices and desktop web browsers.

Using PI System data as the primary data source we are able to stay in touch with operational KPI’s from anywhere.

The chosen platform for creation and implementation of the ‘Grey Screen’ project now in Phase I development.

15



PI Server 2012 – Dominion has upgraded licensing to move to the latest PI Server platform, that will include access to a variety of OSIsoft products.

PI AF, PI Asset Framework. The building block for most of the OSIsoft PI Client tools, we have configured our 1st PI AF Server.

PI Notifications – A Client configurable tool, requiring the PI AF (PI Asset Framework) for implementation.

PI ACE (PI Advanced Computing Engine), capable of a variety of robust calculation solutions.

16


Business Challenge

Determine how Dominion can use the enormous

amount of PI System data in a proactive method.

Dominion historically has used PI System data to help

determine the root cause of failures, and events that lead up

to the resulting issue.

IT provided the Business Unit with some Market available

products that can help move us from a reactive mode to a

preventative mode.

17


Business Challenge (cont.)

Some pilots were performed, and after careful

evaluation and review capital investment

requirements, $,$$$,$$$, a choice was made…..

Why not try this ourselves?

Many highly experienced Operational team members on

staff.

Enormous amounts of operating history in PI Server

archives.

Tools to extract this data, and staff to evaluate.

18


Business Solution

The Operational Excellence Team began developing

a plan:

Determining Phase I points to configure.

Extracting data from PI System via PI DataLink.

Creating a Visibility mechanism – PI ProcessBook Graphics.

Soon after starting, they ran into some logistic issues.

IT PI Support was consulted and a list of project

requirements (Wish List) was developed.

• Displays that could be easily

viewed

• Displays that can fit

screens without any

or little scrolling• Displays that are interactive,

real-time information

• Displays that would not

require mandatory

interaction to deliver vital

information

• Data description – tag details

• Actual Data values

• Real time trending without

switching applications

• 3 Levels of alerting above

and below ‘Normal’

• Viewable alert limits

• Interactive color changes

• Tune-able trigger points

• Plant site rollups• Corporate Level Rollups

• Email and/or text

messaging capable

for alerting• Ability to segregate the data

by plant systems

• Ability to ‘Mask’ trigger points

during plant transitions

• Ability to ‘Mask’ alerts to

minimize false alerts.

• Mobile Accessibility

• Dependable data

source• Dependable delivery

• Maintenance Manageable

• Minimal O&M or

Capital Investments• Use what we have, if

possible

Delivered Solution…..

With the core data being the OSIsoft PI System.

Delivery made using the OSIsoft partner, Transpara

KPI.

Presenting…the Dominion ‘Grey Screen’ solution.

Grey Screens

Why ‘Grey Screen’, what’s with the name

A program that monitors equipment based on 2 year

operating history

Uses Colors to Alert Operating Personnel

Blue (5 to 10 degrees above the 2 year history)

Yellow (5 to 10 degrees above the Blue)

Red (10 degrees above the Yellow)

Grey is Good (Normal)

Why We Needed Grey Screens

– Manufacturers alarms are set so we react to

equipment problems

– Alarm system settings are generally rigid and hard to

change. (Hardware, Software and Control Policies)

– Alarm systems can become an audible nuisance if

settings are too close to the normal operating

conditions

28


What Can the System Do

– Alerts using color changes

– E-mails key personnel when alerts are too high

– Points are easily adjusted and don’t require change

management programs (Alerts not Alarms)

• Example after a turbine outage vibration levels change

– Alerts any piece of equipment that is monitored by

OSIsoft PI System. Much of our non-critical

equipment and older equipment is not alarmed

29


What Can the System Do (cont)

– Alerts can be changed based on the equipment status

(Off or On)

– Alerts can be changed based on ambient conditions

– Helps inexperienced employees identify unusual or

abnormal conditions (Training and Knowledge

Retention)

30


How Did We Make it Happen

– Management support of the vision

– Dedicated team to test and prove value of the

concept

– Executive that approved the money being spent on an

idea

– Dedicated team to train station personnel and sell the

vision that this is their program, not corporate’s vision

31


How Did We Make it Happen (Cont)

– Executive that believed in the program and pushed

management to use it

– Information Technology (IT) expert that knew how to

get the system into the control rooms

32


Dos and Don’ts When Introducing a

Monitoring System

– Do Train all personnel so you get buy in (Eliminate

the Spy in the sky thinking)

– Don’t by pass your work order system by sending or

calling personnel directly when alerts come in.

33


The Results of the Alerting

– ID Fan Vibration Increasing

• Finding low oil level

– Cooling Tower Pump Motor (not monitored in control

system)

• Found the motor wrapped in plastic

– EHC oil pump running on unit that was in an outage

• Control room was not staffed

– Air Pre Heater bearing temperature increasing

• Found lube oil pump running backwards
