CIM Standard

• Allow SW to exchange information about an electrical power system model

• Developed by the electrical power industry, adopted by IEC

• UML Model is used to describe the standard

Modeling electrical grid in CIM• Provides flexibility

• Main CIM standards in focus for GIS to CIM adapter, From IEC61970 and IEC 61968 families:

- IEC61970-301 - Common information model (CIM) base

- IEC 61970-552 - CIM XML Model Exchange Format

- IEC 61970-501 - CIM Resource Description Framework (CIM RDF) Schema

- IEC 61968-100 - System interfaces for distribution management - implementation profiles, interfaces

Modeling electrical grid in CIM

• Flexibility is constrained byprofiles defining detailed data exchange between particularsystems in accordance to anuse case specification.

• Schemes can be derived fromprofiles (e.g. XSD for XML).

„GIS CIM adapter“

• Why GIS as a master system for so many of major CIM Network Model object?

Workflow / business process data are entered first (planning)

• Data vizualization readable more easily by different users

• Data shared easily attributes management shared/secured among groups = quality improved

• Most systems require/utilize geography more or less at some point

• Vision and challenge• Test ArcGIS model through customer projects

• Configurable and flexible GIS CIM adapter

GIS CIM adapterProject case:

Distribution company 131.000 pts.

Operating variety: Urban Coastal & Alpine regions

Full export of network data into CIM –file based / per feeder provisioned early and taken into account at database model design

• Using classification of „topological types“ on GIS objects

• Calculation of CIM topology based on topological types of neighboring GIS features

• Calculating forward and backward differences

• Supporting full and incremental export

• GIS-CIM Adapter maintains current state of CIM topology

Mapping of GIS topology to CIM topology

• GIS objects are extended by MrID is CIM unique ID:

• Primary and Secondary Registration

• GIS Objects are extended by new objects:

• originate from attribute data in GIS

• generated on-the-fly

• GIS - CIM adapter stores all extensions of GIS objects:

• Maintaining of local, GIS IDs

• Maintaining of CIM repository IDs

• CIM Profile definition is crucial

• participants knowledge presents projects risks so reasonably long testing shall be provisioned

• Performance:

• Optimization in terms of database design and data access must be taken into account and incremental export planned

• Positive side effect:

• quality and completeness of data are improved: when providing data to advanced DMS and other operational systems, a small error in data may have huge impact

Summary CIM Projects experience

• GIS CIM Adapter• UT for ArcGIS GIS Model is well suited as a basis to map to CIM while retaining GIS

modelling suitable for other GIS processing• Extensions were developed via configurable „GIS CIM adapter“ to manage numerous

additional CIM objects required

• CIM• Data exchange between systems is a must and by using „CIM“ we avoid to „reinvent the

wheel“ when defining data exchange format between systems. CIM is extensible so it does not set limitations of when we can use it.
