Assessment of the Effectiveness of Two Coordinated Systems: SVC-PSS and STATCOM-PSS for Improving Transient Stability of Power System

Tran Thi Ngoat and Le Ngoc Giang
Abstract—The power system stabilizer (PSS) is a control device provides a maximum power transfer and optimal power system stability. PSS has been widely used to damp electromechanical oscillations that occur in power systems due to disturbances. If no adequate damping is available, the oscillation will increase result in instability case. Shunt static var compensator (SVC) and Static Synchronous Compensator (STATCOM) is also used to improve system stability. This paper focus on the significant of SVC-PSS and STATCOMPSS to improve the transient stability of power system in various abnormal condition. This paper shows the simulation result of model for different fault condition with PSS and without PSS, with SVC and without SVC, with STATCOM and without STATCOM, and show how the Statcom and SVC help to improve the stability when PSS is fail to maintain the stability.

Index Terms—STATCOM, SVC, PSS, power system
