| 摘 要： | 由于功率器件耐压水平和载流能力的限制,传统有源电力滤波器难以实现对高压大容量非线性负载的谐波补偿。为此研究一种新型的适应于中压电网的电流质量调节器。基于该电流质量调节器拓扑结构的特点,提出一种复合控制方法。该控制方法采用瞬时值反馈PI控制和重复控制相结合的方式,利用PI控制器控制低频功率模块,提高整个装置的动态响应速度,利用重复控制器控制高频功率模块,来消除电流跟踪误差。仿真结果表明这种控制策略的正确性和有效性。

| Abstract: | Due to the limitation of voltage level and current capability of power devices,it is very difficult to handle nonlinear loads for the traditional active power filter(APF) in high-voltage high-power grid.Therefore,a novel current quality conditioner for moderate-voltage grid was researched.Based on the characteristics of the topology of the current quality conditioner,a combined control method,which was composed of current state feedback decoupling PI control and repetitive control,was put forward.In this co... |
