SSSC to control Power flow in the Line

Abstract

FACTS controller is the Power Electronics based static controller which enhance power transfer capability and increase controllability of the power system network. Static Synchronous Series Compensator (SSSC) is VSC based controller which is used in transmission network with the aim of utilization of existing line upto its fullest extent. This paper demonstrates transmission line power flow control with the help of SSSC. A control scheme of SSSC is presented to control active power flow in the line. Increase in the power flow in the line is realized with SSSC operation in capacitive mode of operation and decrease in the power flow is realized with SSSC operated in inductive mode of operation. MATLAB simulation studies are demonstrated to validate the SSSC operation.
