Identification of double transmission line shunt faults by using combined DWT and interval type-2 fuzzy logic for digital distance protection
Abstract In this paper, a technique for unerring identification of shunt faults on a transmission line is suggested. This technique is based on discrete wavelet transforms and Interval Type-2 fuzzy logic; six line currents are taken at transmission line relay location. The validity of the recommended technique is demonstrated by simulation research using PSCAD/EMTDC. Simulations were achieved for distinctive varieties of faults thinking about extensive variations in the operating conditions. The recommended technique can identify and classify the fault within the half cycle period and the time taken by this method is less compared to conventional fuzzy methods.
