SFC滤波器谐振分析和处理

目的:通过分析和处理深圳东部电厂SFC无源滤波器谐振问题,指出滤波器在设计时必须避免谐振和保证滤波效果。方法:比较分析计算两个LNG电厂的SFC滤波器和系统的谐振频率及其运行波形。结果:深圳东部电厂SFC滤波器和高压厂用变压器的谐振频率非常接近滤波频率,容易发生谐振,经改造后正常投入运行。

Objective： Expatiating and deal the resonance of the SFC filter in Shenzhen Dongbu Power Plant.Method： Compare、analyze and calculate the resonance frequency and the wave inrunning.Result： It is easy to produce resonance because that the resonance frequency between the SFC filter and the power system in the Shenzhen Dongbu Power Plant is near to the resonance frequency of the SFC filter.
