摘　　要：通过检测和分析石化配电系统中的谐波,指出石化配电系统产生谐波的主要因素是变频器、不间断电源和高压汞灯,提出利用多重化技术减少谐波和采用LC滤波器、有源滤波器治理谐波的方案。根据对电容器与谐波相互影响的分析,提出了在配电系统中结合LC滤波器来合理选择电容器的谐振点谐波次数的改进措施。Based on harmonic detecting and analysis of power distribution system of petrochemical enterprise, it shows that the main sources in the power distribution system of petrochemical enterprise are frequency converter, UPS and HID. Multiple technique, LC filter and active filter strategy were proposed to reduce harmonic component. Based on analysis of the re- lation between capacitor and harmonic component, the improved strategy of selecting resonant frequency of LC filter in the power distribution system of petrochemical enterprise was proposed.
