Abstract The conventional wide-area supplementary damping controller (WSDC) of static Var compensator (SVC) has been investigated. The New England test power system (NETPS) equipped with a SVC is used as the test system. At first, the input wide-area signal of the WSDC is selected by analyzing the controllability/observability of linear model of the NETPS. Then, the residue method is used to determine the parameters of the conventional WSDC. The delay-dependent stability of the closed-loop power system is analyzed. The gain of the conventional WSDC is determined by using the analysis results. Simulation results are presented to show that the designed conventional WSDC of the SVC can improve the damping performances and handle a relative large communication delays.

Key words： Time delays static var compensator wide-area supplementary damping controller geometric controllability/observability
