This paper deals with an algorithm, based on wavelet-Alienation coefficients for protection of wind farm connected distribution network. The proposed algorithm takes the differential current signal of grid node and wind farm coupling node. The Wavelet transform used to extract the approximation coefficients of all the three-phase current signals. Alienation coefficients of each differential phase current obtained over a half cycle is used to identify and categorize the various faults. A modified IEEE13 bus test feeder system used for simulation in MATLAB. Proposed technique tested for detection of all shunt faults at each bus of the distribution system.read more
