摘要:  摘要:提出了一种适用于大规模电力系统暂态稳定性分析的静止同步串联补偿器(static synchronous series compensator,SSSC)机电暂态建模方法。该方法通过合理假设,根据SSSC的数学模型和机电暂态特性,在考虑SSSC直流电压动态过程的前提下建立了SSSC的机电暂态模型。首先,根据SSSC的对外特性建立SSSC的交流侧模型;其次,根据SSSC的自身约束,通过合理假设建立SSSC的直流侧模型;在此基础上,模块化设计了其控制器模型和调制环节模型。仿真结果表明,该模型能较好地呈现SSSC的动态特性,适用于SSSC接入大规模电网时分析其对电力系统暂态稳定性的影响。

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.
