摘　　要：针对配电网10kV高压侧对大容量谐波抑制和无功补偿的要求,提出了注入式混合型有源电力滤波器(IHAPF)拓扑结构。在分析其基本工作原理的基础上,建立了IHAPF的数学模型。针对其数学模型,提出采用递推积分算法进行控制,可以实现给定电流的无稳态误差跟踪和对负载扰动信号的抑制。因为对控制器的实时性要求比较高,采用了双DSP控制器,并对控制器的硬件结构组成以及所包含的软件功能模块进行了说明。实验结果证明了所采用控制算法及控制器软硬件结构的有效性。Focusing on the requirement for harmonic suppression and var compensation with large capacity in high voltage side of the 10 kV distribution grid,this paper proposes the topology of hybrid active power filter with injection circuit （IHAPF）.Based on analyzing its working principle,the mathematical model is built.According to its model,a reeursive integral algorithm is proposed,by which the reference current can be tracked without steady error and the disturbance signal of the load can be suppressed also.Because the requirement for real time is high,the controller with double DSPs is adopted, meanwhile, the hardware structure and each software module of the controller are illuminated.The experimental result shows the validity of the control arithmetic and the soft hardware structure of the controller.
