  1. A Tool for Testing and Fault Diagnosis in IEC 61850-Based Systems Jacques Sauvé, Iony Patriota, Wagner Porto UFCG - CHESF

  2. The Problem • Testing activities for IEC 61850 Substation Automation Systems (SAS) • Conformance testing • Interoperability testing • Functional and performance testing • Our work: Functional Testing • During the design of IEC 61850 SAS • Need a simulator • During the commissioning of IEC 61850 SAS

  3. A Solution • Cigré Workgroup B5.32 • Functional Testing of IEC 61850-Based Systems • Black-box testing • Emulate interactions between IEDs and application • “Test scripts” can verify functional behavior and performance characteristics • Submitted to IEC for standardization

  4. But ... • Need proof-of-concept implementation to test viability in practice • Prototype called Smash • Enables automation engineers to build, run and debug functional tests for IEC 61850-based systems in a simulated environment

  5. Example Scenario

  6. Example Test • Functional Implementation Conformance Statements: • XCBR1 and XCBR2 must trip in less than 100 ms upon inception of an internal short circuit in the transformer

  7. UML Communication Diagram

  8. Test Setup

  9. How to Write Tests Scripts? • WG B5.32 recommends using: • Failure Modes and Effects Analysis (FMEA) • Hazard and Operability Analysis (HAZOP) • … to drive tests writing and check test coverage

  10. A Test Script ...

  11. Smash Architecture

  12. DEMO

  13. Thank You.
