Matlab Computation For Studying Effect Of Location Of Shunt FACTS Devices In Long Transmission Line System

Shunt FACTS devices are used for controlling transmission voltage, power flows, and damping of power system oscillations for high power transfer levels. In this paper the effect of location of a shunt FACT device is investigated for an actual line model of a transmission line. Effect of change of location of the shunt FACTS device to get the highest possible benefit is studied. It is found that the maximum sending end power and maximum receiving end power varies with the location of the shunt FACTS device. The result of actual transmission line model is compared with the result of simplified transmission line model and it is found that in actual transmission line, shunt FACTS devices should be connected before mid-point of the line for maximum benefits. MATLAB codes have been developed in this study.
