Abstract :
This paper presents the applications of the Wavelet Transform (WT) for analyzing fast transient signals originated from fault events in power grids with presence of power electronics-based controllers and its protective devices. The study cases included emphasizes the wavelets ability to discriminate signals originated by the fault events from those injected by power controllers, like the TCSC and its associated protection, the MOV, and determine location and electrical distance of the fault to a reference point. The simulation and analysis are carried out cooperatively mean between PSCAD and MATLAB.
