非线性负载的广泛应用，导致独立电源系统中含有大量的谐波电流和无功电流，严重影响电源的供电质量，有源滤波器通常被用来滤除电网中的谐波电流和无功电流。首先，定性分析引起有源滤波器输出电流相位滞后的原因，并利用Matlab建立系统的数学模型，通过仿真定量分析相位滞后对有源滤波器补偿性能的影响；然后，提出有源滤波器输出电流相位滞后补偿的方法。仿真和实际工程的应用，证明所提方法是有效和可行的。

The use of the nonlinear loads bring large amount of the harmonic current and reactive current and thus affect the quality of isolated power system. Adding the active power filter （APF） in the power system is an effective method to filter the harmonic current and reactive current. First, this article qualitative analyzed the phase lag reason of APF output current, used Matlab to establish mathematic model of the system, and quantitative analysed the phase lag influence on the performance of the system compensation through the simulation system. Then, the phase lag compensation method of APF output current phase was proposed. By system emulation and practical implication of this system, the method was proved to be effective and feasible.
