摘要
为解决有源电力滤波器(APF)采用传统比例控制算法时补偿精度不够高的问题,将比例控制与重复控制相结合的方法应用到有源电力滤波器电流跟踪控制环路中。开展了重复控制环路的参数设计,分析了重复控制环路的稳态精度及动态响应速度,并在15 kVA三相四线制并联型有源电力滤波器装置上进行了实验验证;在满足系统稳定的前提下,分别选取不同的重复控制环路参数实验,指出了最适合该装置工程应用的最优参数。实验结果证明,采用比例控制与重复控制组合的方法能够在保障系统动态性能的同时有效地消除稳态误差。
Aiming at improving the compensation accuracy of the 15 kVA active power filter（ ADF）, the combination of proportional control and repetitive control were applied in the APF. The stability and design of parameter with the control method in APF system were analyzed, and the steady-state error and transient response were also analyzed. The theory was verified by experiment in a 15 kVA three-phase four-wire shunt APF. The performance was investigated under different repetitive control loop parameters, while the system was stable. The results in- dicate that the control method can effectively eliminate the steady state error without reducing the system dynamic performance.
