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

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
