Analysis of a static VAr compensator using the dispatcher training simulator

The static VAr compensator (SVC) has shown great potential among all the voltage stability enhancement measures available. Studies have shown that an SVC, which is properly placed, can also improve the transmission capacity. In this paper, the authors have developed different SVC models for power system dynamics (short-term and long-term) as well as static analysis. With these SVC models imbedded in the dispatcher training simulator (DTS) and associated transient stability simulation, the results obtained by analytical methods, such as the optimal location for installing an SVC as well as the control parameter settings, can be tested, evaluated and tuned under 'real-time' conditions. This kind of implementation could provide valuable assistance for power system planning and operation. The authors have conducted various tests under different operating conditions and using different SVC models to evaluate the influence of major parameter settings. >
