A fault classification technique for transmission lines using an improved alienation coefficients technique

摘要: Summary The recently proposed techniques for detection and classification of different faults are amenable to statistical-based methods such as correlation or alienation coefficients. In this paper, an improved coefficient-based algorithm is proposed. the method, a modified coefficient formula suggested, by which could be identified more accurately. Switching heavy loads also considered in algorithm. The performance method evaluated simulation typical power system conditions. results confirm high capabilities faults. Furthermore, verified using low-scale test bench laboratory. Copyright © 2016 John Wiley & Sons, Ltd.
