摘　　要：直流侧电容电压控制策略是有源电力滤波器(APF)性能优化的关键性技术之一。选用并联型单相有源电力滤波器(SAPF)为研究对象,采用下垂控制器控制策略,调节APF直流侧电压参考值,针对负载突变和电网电压等问题,提出反推自适应PI控制策略。仿真结果表明,较传统PI控制策略,采用下垂控制器与反推自适应PI控制相结合的控制策略响应速度快、稳态精度高,进而提高了SAPF补偿性能。The DC-side capacitor voltage control strategy is one of the key technologies for optimizing the performance of active power filters(APF).This article takes a shunt single-phase active power filter(SAPF)as the research object,adopts a droop controller control strategy,adjusts the DC-side voltage reference value of the APF,and proposes a reverse adaptive PI control strategy to address issues such as load transients and grid voltage.The simulation results show that compared with the traditional PI control strategy,the control strategy combining droop controller and reverse adaptive PI control has faster response speed and higher steady-state accuracy,thereby improving the SAPF compensation performance.
