摘要：
In this paper, a new fault detection method is proposed for protection of transmission lines using RMS values of 3-phase instantaneous powers at both sending end and receiving end. The Input signal of any detection algorithm varies not only in case of faults but also other cases like High Impedance faults and different non fault situations like power swings, CT saturation and frequency deviations etc. Several Detection methods were failed particularly in case of high impedance faults and also at other typical cases. The proposed method is verified for normal faults of different types occurring at different instants and also at various locations. The reliability of proposed algorithm is relatively higher when compared to conventional algorithms. It effectively works under high impedance faults also. The method is tested for various case studies using matlab-simulink software. (C) 2015 The Authors. Published by Elsevier Ltd.
