Overview
IEC TS 62361-102:2018 - "Power systems management and associated information exchange - Interoperability in the long term - Part 102: CIM – IEC 61850 harmonization" defines a practical, use-case-driven approach to harmonize the IEC CIM (Common Information Model) and IEC 61850 information models. The Technical Specification describes how to adapt or extend existing models and/or define new models to enable reliable, long‑term information exchange between substation/field systems (IEC 61850) and business/enterprise systems using CIM.
Key topics and technical requirements
- Use-case driven mapping: Focus on a selected set of use cases (SCADA/EMS/DMS configuration, SCADA commissioning, Volt/Var control, WAMPAC for transient stability) while providing a framework extensible to future use cases.
- SCL ↔ CIM mapping: Detailed guidance for mapping IEC 61850 System Configuration Language (SCL) sections, logical devices, logical nodes and connectivity models to CIM classes and profiles.
- Measurement and control mapping: Rules for mapping measurements, logical node data objects, switch positions, power flow direction, and control models between standards.
- Real-time data exchange: Recommendations for identifying measurements, mapping common data classes and qualities, and interoperability with protocols (examples include IEC 60870 and IEEE 1815/DNP3 mappings).
- Harmonization recommendations: Proposals for standard extensions and naming/identification conventions, equipment type codes, phase and voltage modelling, layout coordinates and drawing syntax.
- Consideration of existing standards: Semantics, services, protocols and architecture are considered to ensure backward compatibility and future growth.
Applications and who should use it
IEC TS 62361-102 is practical for:
- Grid operators and utilities implementing integrated SCADA/EMS/DMS workflows that require consistent information exchange between substations and enterprise applications.
- System integrators and vendors building gateways, data-model translators, or configuration tools that must translate SCL to CIM or vice versa.
- Protection, automation and control engineers involved in Volt/Var control, commissioning or WAMPAC deployments requiring harmonized semantics.
- Standards committees and architects designing future CIM or IEC 61850 extensions and joint working groups.
Benefits include improved interoperability, reduced manual configuration effort, clearer mapping of measurements and controls, and a framework for long‑term model convergence.
