摘要

Thyristor-controlled series capacitor (TCSC) compensated transmission lines (TLs) are increasingly used in recent years for transmission of bulk power generated by doubly fed induction generator (DFIG) based large scale wind farms. However, the typical fault characteristics of DFIG and TCSC affect the performance of conventional distance relays. To solve the problem, in this article, a new relaying algorithm is proposed that utilizes sign of the half-cycle superimposed positive-sequence current for fault detection, empirical mode decomposition assisted random forest classifier for fault classification and modified impedance approach for fault location estimation. The performance of the proposed relaying algorithm is evaluated on various fault and nonfault cases generated on a test power system using MATLAB/Simulink and OPAL-RT (OP4510) manufactured real-time digital simulator environment. Also, compared with few existing approaches. The demonstrated results justify the merits of the proposed relaying algorithm for protecting the TCSC compensated TL connected with DFIG-based wind farm.
