Abstract
This paper presents an approximate level Discrete Wavelet Transform (DWT) based differential relaying scheme for a transmission line in the presence of Unified Power Flow Controller (UPFC), Wind farm and Photo voltaic (PV) module. The fault current signals are obtained from respective buses and pre-processing it with the help of approximate level DWT to derive fourth level approximate coefficients (CA4). Further, the RMS value is extracted to compute operating and restraining values for fault detection in such a complex transmission system. The proposed relaying scheme has been extensively tested for wide variations in parameters and operating conditions, and the performance shows that the proposed scheme is highly reliable.
