Abstract

Abstract: ABSTRACT： This paper proposes an electromechanical transient modeling method of static synchronous series compensator （SSSC） for large-scale power system transient stability analysis. Through reasonable assumptions, according to the mathematical model and electromechanical transient characteristics of SSSC, this method establishes the electromechanical transient model of SSSC with considering the DC voltage dynamic process of SSSC. Firstly, we construct the AC-side model of SSSC according to the external features of SSSC, and then, construct the DC-side model according to the own constraints of SSSC. On this basis, we implement the modular design of its controller model and modulation model. The simulation results show that this model presents the dynamic characteristics of SSSC effectively, and is appropriate for the influence analysis of SSSC access into large-scale power system on the transient stability of power system.
