Effect of Series Compensation on Optimal Position of Series-Shunt Flexible Alternating Current Transmission System (FACTS) Device for a Long Transmission Line

The aim of the article is to present an analysis which has dealt with the effect of series compensation on the optimal position of a series-shunt connected FACTS device of a transmission line. TheFACTS device has been used in a line model called ‘actual transmission line model’. The transmission line was long and had a series compensation at the center. A Matlab based simulation had been used to investigate the effect of series compensation of thetransmission line on the optimal location of a seriesshunt FACTS device and finally, the optimal position of the series-shunt FACTS device was identified. The result of the study revealed that with the change of the level of series compensation values (Zc) the optimalposition of a series-shunt facts device was changed. The results of this work were very useful in optimizing the location of various series-shunt FACTS devices in order to acquire an efficient long transmission line. Therefore, a cost effective and efficient installation of FACTS devices by diverting the optimal location ofFACTS device near the substation was also achievable by this simulation
