Abstract
This paper presents a distance relaying algorithm for transmission line compensated with Static Synchronous Series Compensator (SSSC). The compensation voltage driven by SSSC is calculated from the line current measured at a relaying point Then the compensation voltage is subtracted from the voltage measured by the relay. We can apply conventional distance relaying algorithm with this subtracted voltage to locate a fault. The results of case studies using EMTP (Electro-Magnetic Transient Program) show the proposed algorithm has higher precision.
