Performance of directional relays using SVM classification with Double-Line-to-Ground faults

Abstract

Directional relays may be a good solution for the protection of MV distribution networks with distributed generators (DG) [1]-[3]. In more advanced protection scheme, with some protections distributed along the feeders [4]-[5], the directional algorithms without voltage sensors would be more interesting because of investment cost reduction. These algorithms use only sequence current ratios (i.e. ∆I -/∆I0 and ∆I -/∆I+) coupled with a SVM classifier to determine the fault direction [6]-[7]. In this paper, the algorithms will be analysed in the case of double-line-to-ground faults: theoretical base is explained; offline simulations are performed with Simulink/SimPowerSystems. The simulation results are subsequently used for training SVM classifiers.
