  1. Communication in Substations:IEC618501.4 : INTEROPERABILITY Sudhakar RAMPURKAR / AnshumanBHALLA 26th & 27th October 2009

  2. Interoperability • Ability of two or more IEDs from the same vendor, or from different vendors, to exchange information and use that information for correct execution of specified functions Has a DATA MODEL model that can be accessed Request IED Intelligent Electronic Device Response The WHAT to exchange (IEC 61850-7-3 &4) Event The HOW to exchange (IEC 61850-7-2)

  3. IEC 61850: Interoperability, cont. I • What is needed for interoperability • Common standardised: • Language (data model) • Services (service model) • Protocol • Communication medium • Engineering data exchange • Conformance test • IEC 61850 standardised these needs

  4. IEC 61850: Interoperability, cont. II • IEC 61850 does not automatically ensure interoperability • To reach interoperability a well-done engineering is necessary • IEC 61850-4 System and project management Clause Engineering Requirements • IEC 61850-6 Configuration description language for communication • Conformance Testing will be an important part to provide interoperability • IEC 61850-10 specifies the conformance testing

  5. IEC61850 documentation needed Protocol ImplementationConformanceStatement (PICS) • Summary of the communication capabilities of the system or device (for testing) • Protocol Implementation eXtra Information for Testing (PIXIT) • Communication capabilities of the system or device which are outside the scope of the IEC 61850. The PIXIT shall not be subject to standardisation Model ImplementationConformanceStatement (MICS) • Details the standard data object model elements supported by the system or device Tissue Implementation Conformance Statement (TICS) • Details the Tissues (Technical Issues) that the IEC61850 implementation has incorporated

  11. Conclusions • Conventional testing requires hard wiring, while in IEC61850, it may be partially or completely communications based. • Comparison between the performance of hard-wired and communications based solutions is required to confirm that IEC61850 can be successfully used to replace conventional substation control and protection systems without any degradation in the overall performance of the system.
