摘　　要：通过数学推导得出了静态同步串联补偿器(SSSC)的功率传输特性及包含交直流系统的详细数学模型。数学模型对SSSC的交流部分和直流部分分别进行分析和数学建模,并通过交、直流侧功率守恒将二者联系在一起。利用EMTDC提供的元件库,搭建了含单机无穷大系统及SSSC装置的仿真系统。SSSC装置包括二电平、六脉冲电压源逆变器及其SPWM脉冲发生回路。利用EMTDC中的控制模块构建了典型的PI控制回路,实现对线路潮流的实时控制。仿真结果验证了SSSC功率传输特性及其数学模型的正确性。The steady state performance and mathematical model were presented, which included alternating current and direct-current system. The AC part and DC part of SSSC were analyzed and modeled separately and combined through power conservation law of both side, so the integrated model of SSSC was made. The simulation model of SSSC was derived by EMTDC, the single machine infinite bus system and detailed model of SSSC were simulated. The sinusoidal pulse width modulation （SPWM） approach was adopted for the voltage source converter （VSC） to producing fire pulse. The mathematic model and steady state performance are tested by simulation model and the result of simulation is satisfied.
