Fault Zone Detection on Advanced Series Compensated Transmission Line using Discrete Wavelet Transform and SVM
نویسنده
چکیده
In this paper a novel method for finding the fault zone on a Thyristor Controlled Series Capacitor (TCSC) incorporated transmission line is presented. The method makes use of the Support Vector Machine (SVM), used in the classification mode to distinguish between the zones, before or after the TCSC. The use of Discrete Wavelet Transform is made to prepare the features which would be given as the input to the SVM. This method was tested on a 400 kV, 50 Hz, 300 Km transmission line and the results were highly accurate. Keywords—Flexible ac transmission system (FACTS), thyristor controlled series-capacitor (TCSC), discrete wavelet transforms (DWT), support vector machine (SVM).
