For historical reasons, IEC standards are based on several different models:
• IEC 61850 for substation automation and other device level applications
• Common Information Model CIM (IEC 61970, IEC 61968, IEC 62325) for control centre
applications
• Companion Specification for Energy Metering (COSEM) for metering
Reference: IEC 62357-1 TR: Power systems management and associated information exchange –
Part 1: Reference architecture
The Problem #1Power systems are complex – multiple groups have worked on different aspects

• “an abstract model that represents all the
major objects in an electric utility enterprise
typically needed to model the operational
aspects of a utility … as well as the
relationships between them”
• IEC 61970-301 defines the CIM Base set of
packages … functional aspects of an
Energy Management System including
SCADA
• Typical application - state estimation
Common Information ModelDesign aim: facilitates the integration of EMS, DMS and other control centre applications
Page 7Confidential Property of Schneider Electric |
• Define a short list of use cases that link control center applications and substation automation
• Fundamental use case : Configuration of real time communication between substations and control
centres
‒ Extends the top-down engineering process described in IEC 61850 part 4 and 6
‒ Adds steps related to the network models within SCADA/EMS/DMS in the control centre
• Define mapping between the two models
• Identify where the models overlap, and where they are different
• Make recommendations for revisions to reduce ambiguities and make transformations easier
ApproachOne use case at a time …

1. Planning department produces requirements
2. IEC 61850 System Integrator
• Defines formal electrical model and export as System Specification Description (SSD) file
• Imports capability descriptions for Intelligent Electronic Devices (IEDs) and links to the electrical model
• Defines the communication configuration and export as System Configuration Description (SCD) file.
3. Network model manager
• Transforms into a CIM based modelling tool for review
• Adds any additional CIM information
• Applies incremental update for the SCADA/EMS/DMS control centre systems
4. Commissioning - verify all the communications
Use case – principal actors and main stepsConfiguration of real time communication

• WHERE is the measurement, WHAT does it mean
• IEC 62361-102 CIM - 61850 Harmonization (scope of this presentation)
• HOW, WHEN, WHY
• IEC 61850-90-2: Using IEC 61850 for communication between substations and control centres
• IEC 61850-80-1: Guideline to exchanging information from a CDC-based data model using IEC 60870-
5-101 or IEC 60870-5-104
• IEEE 1815.1 - Standard for exchanging Information between networks implementing IEC 61850 and
IEEE Std 1815™ [Distributed Network Protocol (DNP3)]

SCL: “a file format for describing communication and parameters related to IED (Intelligent Electronic Device)
configurations, communication system configurations, switchyard (function) structures, and the relations
between them” [IEC 61850-6]
Specific subsets of the language are used for configuring a system or configuring individual IEDs.
Sections in an SCL file
• Substation / Line / Process identifies the equipment and associations to Logical Nodes in the IEDs
• IED Descriptions the logical nodes within each physical IED
• Communications connections between IEDs
• Data Type Templates details of the data models
IEC 61850 System Configuration description Language (SCL).
Substation equipment identification and one line
connectivity description has a similar business
requirement within IEC 61850 based system
engineering tools and within CIM based
network engineering tools.
The mapping to CIM should be possible from a
SSD description before any IEDs or Logical
Nodes Types have been defined.
SCL defines equipment type codes
CIM defines equipment type classes
Recommendation R2: The list of device type
codes … should be extended to correspond
better with the Common Information Model

IEC 61850 Logical Node = a group of data
objects (status, measurements controls,
settings, description)
CIM and traditional SCADA protocols use data
points with a value, quality and time
IEC 61850 allows systems to be designed and
configured using fewer but more complex
objects
Some data objects in some types of logical node
correspond with CIM measurements

Mapping Data Objects for Status and MeasurementsIEC 61850-7-4 defines over 600 status or measurement data objects
IEC 61970-301 and -452 define only 19 standard MeasurementTypes
Page 16Confidential Property of Schneider Electric |
Recommendation R13: CIM based standards should use selected IEC 61850 data object names as
MeasurementType names.
OR
Recommendation R14: [Alternative to R13] add a new attribute in the CIM Measurement class called
IEC 61850 DataObject, which is an enumeration and the value will be any data object that is defined
in IEC 61850
Mapping other Data Objects.
