PERFORMANCE OF MOV- PROTECTED THREE PHASE SERIES COMPENSATED TRANSMISSION LINE
Main Article Content
Abstract
In this paper simulation of three phase transmission line with series compensation in fault condition is represented. Compensation to transmission line is compensated by series capacitor means fixed series compensation is used. Series capacitor is used with its protective equipment. Metal Oxide Varistor and Air Gap with RL damping circuit are used to protect series capacitor from overvoltage. The purpose of series compensation of long transmission line is to reduce inductive reactance of transmission line and to enhance power transfer ability. This paper represents simulation study in MATLAB/SIMULINK and shows results for single line to ground fault and three phases to ground fault.
