Identification of Faults in Power System Using Fuzzy Logic Technique
Power reliability and quality of electrical power supply is mostly affected by occurrence of faults in transmission/distribution network. To reduce the time of power outages and for the immediate restoration, the fault identification method must be very effective. Under faulty condition system operator receives very complex information difficult to make decision on restoring a tripped feeder to normal operation. Hence, to build the decision making ability effectively, fuzzy logic based fault diagnosis method is presented in this paper. This method can classify and identify the ten types of shunt faults that occur to Radial topology of transmission/distribution network. This method uses three phase feeder current, neutral current and phase voltages as input to the fuzzy inference system (FIS)
