Adjusting the Transient Stability of Power System Using STATCOM-SMES Combined Compensator

Since most of the new FACTS devices are operating in compensating active and reactive power and most of the electrical energy saving systems have an acceptable operation in compensating active and reactive power, in this paper a combined compensator of STATCOM-SMES is introduced and is exploit in order to adjust the transient stability of power network. The purpose of this paper is analyzing the more effective operation of combined compensator of STATCOM-SMES comparing with STATCOM compensator, using an appropriate strategy in adjusting the transient stability. To do this, a single machine infinite bus is assumed as sample system and using combined compensator in sample power network, appropriate results are shown for adjusting transient stability. Simulations are carried out using PSCAD/EMTDC.
