End-to-end testing of protection schemes: an utilities experience
Sharing knowledge - paper of the month
Application oriented end-to-end testing is a system test that focuses on the validation of protection schemes independently of protection relay type and settings. Fault values for tests are based on actual system parameters and plant characteristics rather than idealised values which are used in conventional steady state protection testing methods.
The following paper describes a utilities approach to end to end testing, from traditional steady state methods to the evolution of application oriented testing to test a complex extra high voltage (EHV) over line protection scheme, and outlines the test methodologies used and the issues identified.
