摘要 并联有源滤波器(APF)需要对不同频率的谐波电流实施跟踪控制,采用同一时间尺度控制很难实现对各次谐波电流的高准确度跟踪。提出一种基于APF的新型零静差电流跟踪控制算法,该算法使用基于傅里叶级(FS)数建立的多时间尺度同步旋转坐标系和比例积分运算(PI)。相对于常规的零静差控制算法,如比例谐振控制(PR),向量PI控制(VPI)等,提出的零静差电流跟踪控制算法增强了系统频率漂移适应性和抗干扰能力,尤其对高次谐波更加明显。对该控制算法的开环传递函数和闭环传递函数进行了详细分析。仿真和实验结果验证了该算法的有效性。

Abstract:An active power filter (APF) can compensate harmonic currents with different orders. However, the compensating accuracy for different order harmonics varies largely based on one time scale controlling method. A novel zero steady-state error current control strategy for shunt active power filters (APF) is proposed based on Fourier series (FS) using multi-time scale synchronous rotating frame. Compared to general zero steady-state error control algorithm, such as proportional-resonant (PR) and vector PI (VPI) control, the proposed strategy weakens system frequency shift effect and enhances anti-interference ability. With a mathematical model, the open-loop and close-loop transfer functions of a control system are analysed in detail based on FS. Simulation and experimental results have verified the proposed current control strategy.
