摘　　要：基于 MATLAB中的 SIMULINK仿真工具 ,建立了电容型静止补偿器 (ASVG)的仿真模型 ,并对其静态特性和动态特性进行了全时域仿真分析。通过对仿真结果的分析 ,得出了 ASVG的输出电压与它和系统接入点电压间的相角差、ASVG晶闸管触发脉冲、触发脉宽之间的关系 ,这为ASVG的触发脉冲和触发脉宽的设计提供了依据。同时 ,文中还对影响电容型 ASVG静态输出 (或吸收 )的有功功率和无功功率的因素进行了详细的分析。最后 ,通过对 ASVG受扰后暂态响应曲线的分析 ,提出了一种 ASVG的动态响应模型。Based on SIMULINK, a simulation tool of MATLAB, a detailed time domain model of the advanced static VAR generator (ASVG) with capacitor as its energy storage device is developed in this paper. The steady state and dynamic characteristics of ASVG are analyzed with the help of this model. The research is mainly focused on the following aspects: (1) The relationship between the trigging angle of GTO, the trigging pulse width and the angular difference between the output voltage of the ASVG and the voltage at the point where the ASVG was connected; (2) The main factors which affect the active and reactive power outputs of this type of ASVG. At last, a mathematical model representing the transient characteristics of the ASVG is obtained from the simulation results under different disturbance.
