摘要: 分析了引起有源电力滤波器(APF)补偿电流相位滞后的原因,建立了相应数学模型,并利用MATLAB仿真研究了相位滞后对有源电力滤波器补偿性能的影响,提出了一种输出补偿电流零相位滞后的超前校正方法,实现了与电源中相应分量的相位同步。最后通过仿真和实际工程应用,证明了该补偿方法的可行性和有效性。Abstract: The reasons of the compensation current phase-lag of active power filters (APFs) is analyzed in detail, the corresponding mathematical model is set up, and the phase-lag to influence of compensation performance is described as well by MATLAB. After then, a lead correction method of compensation current with zero phase-lag is proposed to implement the phase synchronization of supply source components. The simulation and actual application results show the feasibility and validity of the proposed method.
