| 摘 要： | 在采用有源电力滤波器消除谐波中,由于滤波器的检测精度、指令电流计算延时和输出滤波器的相移等因素的影响,滤波效果不是很理想.提出了应用于并联型有源滤波器的比例递推积分控制算法,比例系数和积分系数由模糊推理在线整定.该算法能有效地提高系统的动态和稳态性能,可适应于单相、三相三线制、三相四线制非线性负载电流波形畸变的抑制.实验结果证明了所提出的控制算法的有效性.

| Abstract: | In the use of active power filter for eliminating harmonics in the electric power system,the performance of active power filter is not satisfying due to the influence of detection accuracy,time delay of instruction current calculation and phase displacement of output filter.This paper presents proportional recursive integral controller applied for parallel active power filter to improve its steady_state and dynamic performance.The parameters of the controller are on_line tuned by fuzzy inference to enhance self_adaptive ability of the system.It can be applied to single phase,three phases three wires and three phases four wires active power filters. Experimental result confirms the validity of the proposed controller. |
