Recently, series compensation is widely used in transmission. However, this creates several problems to conventional protection approaches. This paper presents overcurrent protection and fault classification approach for series compensated transmission line using support vector machine (SVM). Postfault three lines current samples for half cycle are used as inputs to SVMs. The time taken for fault classification is 10 ms after the fault inception. Four SVMs are used; three SVMs (SVMa, SVMb and SVMc) are used for faulty phase detection and last SVM (SVMg) is used for ground detection. The polynomial kernel SVM is designed to provide the optimal classification conditions. …
