Power system performance improvement by using an SVC device

This paper presents the performances of the static VAr compensator (SVC) in controlling the voltage under various perturbations that may occur in the transmission power system. By controlling the voltage, SVC is indirectly contributing to the enhancement of the loading capability of the transmission network. Simulations were performed on the test network called TEST2 using the EUROSTAG software. Both static and dynamic simulations were performed, while analyzing the voltage control and the change in the reactive power under various disturbances, as well as the power losses under steady-state.
