Abstract
This paper proposes a relaying technique for recognition of faults in a series-compensated transmission line (SCTL) connected with wind energy conversion system (WECS). The proposed relaying scheme is designed using coiflet wavelet transform (CWT) which is used to recognize the fault and identify the phase type involved in the fault, based on the amplitude of energy content in the CWT coefficients, in a relaying of transmission line. The samples of three-phase fault currents are recorded at Bus-1 of the system and are then processed using CWT. Thereafter, the amplitude of energy content hidden in the CWT coefficients is calculated. The practicability of the CWT-based relaying technique is tested on a SCTL connected with WECS under numerous fault situations using MATLAB, and the simulation outcomes demonstrate that the CWT relaying technique is effectual and precise.
