摘　　要：在介绍有源电力滤波器(APF)工作原理及电力系统谐振原理和谐振频率计算的基础上,针对APF在工程应用中与电容补偿柜并联运行时存在的谐振和可靠性问题,提出了具有工程应用价值的串联电抗法以及改变APF采样回路的方法,最后通过实际的工程应用案例验证了该方法的可行性。Firstly,working principle of Active Power Filter(APF)and the power system harmonic principle are explained on the basis of the resonance frequency. Then,an engineering approach is raised and studied to resolve the harmonic resonance problem when APF is working in parallel with capacitor compensation cabinet,which includes adding serial reactance and changing APF CT sampling circuit. At last,feasibility of this approach is verified by actual engineering case study.
