Abstract

In this paper a comparison is made between the conventional shunt compensator (Static Var Compensator, SVC) providing only reactive power modulation and the GTO-based advanced compensator (Static Condenser, STATCON) providing both active and reactive power modulation, regarding their effectiveness in damping power oscillations. Based on small purturbation analysis, the damping efficiency in terms of the real power flow change caused by a change of the compensating reactive or real power is calculated and compared. Also, the dependence of the damping on the compensator and load location is investigated
