Abstract

A new scheme for fault identification during power swings is proposed in this paper. The new scheme is based on the orthonormal wavelet transform algorithm. The main advantage of the proposed scheme is that fault occurring in the transmission line can be correctly identified during different kinds of power swings. Details of applying the proposed scheme in the distance protection are discussed in the paper. The effectiveness of the proposed scheme was verified with the data sampled from an EMTP based simulator. Furthermore. As only limited number of real value calculation is needed for the proposed scheme. It is easily realized in real-time applications
