Intelligent fault diagnosis of electrical power transmission network using FPGA

This paper introduces a new algorithm based on FPGA to diagnosis the faults in electrical power transmission network. The fault diagnosis system can provide a general description of the malfunctions of protective devices. To handle malfunctions of various protective devices such as differential relays, over current relays and Breaker Failure Devices(BFD), malfunction analysis of these protection devices has to be included in the fault diagnosis system. In recent years, several authors have proposed logic based systems for fault diagnosis involving various fault types and protective device malfunctions [1-2]. This paper demonstrates the feasibility of applying FPGA to power system fault diagnosis of electrical power transmission network.
