摘要
对徐矿集团张小楼矿6 kV供电系统进行了谐波跟踪测量,通过对数据的研究分析,查出谐波产生的根源。在分析研究国内外谐波治理方案的基础上,结合矿井自身的特点,通过调研对比,发现SVG静止无功发生器的无功补偿和有源滤波功能,不仅对张小楼矿井的改造有很好的治理效果,同时还具有节约成本、回报率高等特点。且SVG静止无功发生器安装前后数据对比表明:其无功补偿和有源滤波功能明显,具有很高的经济效益和实用价值。
By a long time tracking and measuring to the 6 kV power system harmonic and though the analysis to the data in Zhangxiaolou mine,the root which cause harmonic have been dentified.Combine the mine＇s own characteristic with the analysis of various domestic and international technology controlling to the harmonic,not only the founction reactive compensation and filtering of the SVG has a good control effect on the transformation of Zhangxiaolou mine,but also it has other characteristic,such as savings and high rate of return.In addition,the SVG data comparison before and after installation shows that：it＇s reactive power compensation and active filtering function significantly,and have high economic and practical value.
