Study of power system transient stability using FACTS and SDR

Electric power systems are becoming more and more complex and large-scale. Therefore, stabilization and voltage stability problems of power system are taken seriously. In this paper, by using the FACTS technology, the new system stabilizing technique was proposed, and the following were executed: computer simulation and experiment using transmission simulator. The effectiveness for the stabilization was shown in that a system swing was damped by the on-off control of the parallel and serial resistor.
