摘　　要：有源滤波器直流侧电压的波动对有源滤波器的稳定运行有很大的影响，针对这个问题，通过分析直流侧电压波动产生的原因及对有源滤波器运行的影响，进一步对传统PI控制提出了基于电压偏差平方的PI控制的改进方法，这种控制直流侧电压的方法对处理传统PI控制的非线性问题有很大的转变。并通过matlab仿真验证了改进的PI调节控制策略对谐波的消除有很好的效果，这种控制策略通过软件即可实现，不需要增加硬件设备，是一种经济的解决途径。DC-side Voltage fluctuation is a great impression for stable of Shunt Active Power Filter （SAPF）, according to this issue, the DC-side voltage fluctuation cause and influence on the performance of the SAPF are analyzed, put forward the square of the voltage deviation based on PI control method for the traditional PI control, it has a great improvement for dealing with the nonlinear problem of traditional PI control. And the matlab simulation proves good effect for the harmonic elimination, this harmonic elimination control strategy can be realized through software, no extra complex hardware needed, and is an economical solution
