Abstract
Abstract—Relay misoperations play an important role in cascading events. This paper proposes a novel strategy to monitor and verify relay operations during disturbances. Neural network based fault detection (NNFD) algorithm and Synchronized sampling based fault location (SSFL) algorithm are combined as an advanced fault analysis tool to give the precise fault information. Event tree analysis (ETA) is used for comparing relay operations in the real system with expected relay actions. Corrective actions are introduced if relay operations are contributing to cascading events. A case study is given in this paper to help better understanding of the entire strategy. Keywords—event tree analysis, fault diagnosis, fault location, neural networks, power system faults, power system protection, protective relaying, synchronized sampling.
