Fault locating transmission lines with thyristor-controlled series capacitors By fuzzy logic method

Abstract

Presently, with the increasing competition due to the privatization of the electricity industry and the desire to provide better services to customers with critical loads. It has led to the development of speed and reliability of fault locating methods for transmission and distribution systems. It can be difficult to locate the fault. There are various methods for locating in series compensated lines with series equipment. This paper presents a novel fault locating algorithm on series compensated lines with the presence of Thyristor Controlled Capacitor Compensator (TCSC). The proposed algorithm was presented and the simulation was modeled in MATLAB software. The results show that the proposed algorithm increases the accuracy and at the same time speeds up the detection of the fault location in the series compensated transmission lines in order to prevent the malfunction of the relay operation.
