| 摘 要： | 论述ASVG的工作原理,根据控制原理设计ASVG的模糊PI(Fuzzy-PI)控制器.采用模糊控制器获得良好的动态性能,同时引入PI控制改善模糊控制器的静态性能,增强其鲁棒性.该控制器使系统在电流跟踪误差较大时比例控制占主导,误差减小速度较快,在误差减小到一定范围内时积分控制占主导,实现稳态无差.并且该控制器具有较强的自适应控制能力,增强了对电力系统稳定性的控制,具有满意的控制精度,易于实现数字控制,比传统的PI控制具有更好的控制效果.数字仿真验证了该控制方法的有效性和正确性.

| Abstract: | The principle of advanced static var generator(ASVG) is described in this paper,the Fuzzy-PI controller of ASVG is designed according to the control principle.It can get good dynamic performance when Fuzzy controller is used.The PI control is added to improve the static performance of the controller and strengthen its robust.The P-control is dominating when the error is bigger,then the error is dimi-nished and the speed is quicker.The I-control is dominating when the error is small and the system gets up to... |
