Computational simulation demonstrates accurate faulted-phase identification in overhead distribution systems using modal and wavelet transforms, highlighting improved fault classification for...
An identification of faulted phase in overhead distribution System is presented in this paper. This technique is accomplished by two steps. First, to identify the type of fault polarity (grounded or ungrounded). Then, determine the faulted-phase type. The proposed method takes the advantage of the special features of Clarke modal transformation and wavelet transform to explore the type of fault occurring along the distribution power system. MATLAB software is used for implementation of modal and wavelet transformation. ATP/EMTP is used for simulation results of the sample distribution system for demonstration and testing of the proposed method.
