Abstract
In Distribution Network, Distribution Static Synchronous Compensator (D-STATCOM) generally uses double closed-loop control strategy, in which the DC side voltage needs to keep stable with the conventional PI controller. But the conventional PI controller is easy to make the D-STATCOM non-linear, and have a large overshoot and static error, and the response speed is slow, and its parameter is very difficult to be selected. So it is difficult to meet the control requirements. In order to solve the problems, this paper designs the Fuzzy Immune PI controller to maintain the stability of the DC side voltage combining the immune feedback mechanism and Fuzzy Controller with the conventional PI controller. The simulation results show that this controller has more advantages than the conventional PI controller, and can stabilize the DC side voltage.关键词
