摘要
在对传统LC滤波器性能分析的基础上,以开滦煤矿矿井提升系统为例,分析了可能存在的电网谐波源及其各次谐波,提出了改进的滤波电路,通过Ks-f曲线分析验证,该电路可以大大改善对五次谐波的滤波效果。
Based on the performance analysis of the traditional LC filter, the harmonic component and different times harmonic are discussed regarding the hoister system of Kailuan coal mine as the example, a improved filter circuit is put forward that can reduce the influence of the fifth time harmonic through K. - f simulated curve.
