Why system-based testing should be part of every commissioning

Virtual Event

Gone are the days where misoperation of a relay was found in temperature, vibration and other influences that caused the relay threshold to drift or case complete mechanical failures. Since the introduction of the first digital relays, the power and complexity of protection relays have continued to grow. Due to now affordable communication technology a relay is now part of a bigger protection scheme. As a result, the causes for misoperations have shifted towards logic, settings and design errors but so far testing did not adapt. It is time to rethink our testing procedures. With limited testing time and resources, we have to invest our efforts, where we can actually find errors and prevent misoperations. System-based test approaches are well established in end to end testing, where the test case is derived from a power system simulation of a real-world fault scenario. This principle is now further improved to be applicable for every protection scheme with minimal effort. In this talk, Maryam will share what system-based testing can reveal compared to the conventional relay settings tests. Examples of different field tests performed, and problems found via system-based testing will be examined and the importance of system-based testing for the future of every commissioning will be discussed.
