Model Based Testing and Diagnosis of IEC 61850 Systems

This article describes the methods used for testing and fault diagnosing through a proof-of-concept prototype developed in a research project.

The adoption of the IEC 61850 standard on Substation Automation Systems (SAS) requires new ways of testing and diagnosis. Testing is required to ascertain their correct behavior, while diagnosis is required to find and correct any faulted functions detected in a test. The object-oriented aspects of IEC 61850 suggests a model-based equivalent concept for testing and diagnosis. This issue has been partially addressed by Cigré Working Group B5.32 in proposing a structured object-oriented methodology for Functional Testing of IEC 61850 Based Systems. More
