摘　　要：为了解决有源滤波器用于电压源型负载系统时出现的谐波放大问题,本文提出在电压源型负载输入侧增加输入电抗的方法。结合某化工厂实际应用系统,先从理论上分析增加输入电抗对谐波放大系数的影响;然后借助PSIM仿真软件搭建三电平有源滤波器在该系统的应用仿真模型,分别对不同电感下的谐波放大系数进行仿真。最终结合现场实际情况确定了最优的输入电抗参数,有效抑制了谐波放大现象,实现了三电平有源滤波器在该电压源型负载系统中的合理应用。In order to solve the problem of harmonic amplification when active power filter is used in voltage source load system,a method of adding input reactance to the input side of voltage source load is proposed.Combined with the practical application system of a chemical plant,the influence of increasing input reactance on harmonic amplification coefficient is analyzed theoretically;then the application simulation model of three-level active power filter in the system is built with the help of PSIM simulation software,and the harmonic amplification coefficient under different inductance is simulated respectively.Finally,the optimal input reactance parameters are determined according to the actual situation,which can effectively suppress the harmonic amplification phenomenon and realize the reasonable application of three-level active power filter in the voltage source load system.
