摘　　要：根据低压电力用户的动态无功补偿需求,对静止无功补偿系统(SVG)的控制策略进行研究,对常规的间接电流控制进行改进,提出一种电流开环矢量控制的方案,以改善动态性能。论述了其原理,利用MATLAB的SIMULINK工具对该系统进行建模和仿真,结果证明:SVG使用此控制策略能更加快速、准确地响应电网系统的无功功率变化,更好地实现对系统无功功率的动态补偿。According to the needs of the low voltage electric power users＇ dynamic reactive power compensation, the control strategy of static var generator（SVG） is studied, On the basis of normal indirect current control a new control scheme of vector control without current loop is put forward to improve the dynamic performance. Its theory is explained in detail and the whole system is modeled and simulated by employing MATLAB/SIMULINK. The simulation result proves that with this strategy SVG can response the variation of the system reactive power faster and achieve the dynamic compensation of the system reactive power.
