abstract
This paper provides an overview of the scope and methodology for transient relay testing. The scope of transient relay testing is divided into: a) conformance test for examining the functionality and generic performance characteristics of relays, and b) application test for analyzing the specific performance issues and trouble-shooting relay misoperations. For conformance test, the methodology including system modeling, automated generation of test scenarios, relay modeling, and implementation of automated relay testing is discussed in detail. For application test, the key issue is the selection of typical scenarios for analyzing the relay behavior in vulnerable system conditions. A view about benefits and approaches of transient based relay testing is explained in this paper. 2006 IEEE.
