冶金轧钢厂的谐波治理

HARMONIC TREATMENT IN ROLLING MILL

利用中间谐波分析方法 ,准确地分析出马钢两个轧钢厂的谐波结构情况。在此基础上重新设计了滤波器参数 ,按照尽可能利用原滤波元件、降低改造费用的原则 ,对设计参数作进一步优化。改造后的滤波器投运两年多 ,获得成功。从而证明 ,利用中间谐波分析方法 ,治理轧钢厂电能质量 ,是一种国内先进的方法。

Interharmonics analysis is used to analyze accurately the harmonic structure in two rolling mills of Magang.Filter parameters are redesigned on this basis.The design parameters are further optimized according to the principle of using the original filter parts as far as possible to reduce the improvement cost.The improved filter has been put into operation successfully for more than two years.It has been proved that using interharmonics analysis method to treat electric energy quality in rolling mill is an advanced method in China.
