摘要
针对谐波污染会导致电网电压与电流发生畸变、浪费电网容量等问题,结合上海大屯能源股份有限公司姚桥煤矿的实际情况,进行了电能质量测试及分析,提出了采用SVG进行谐波治理及无功补偿的方案。谐波治理及无功补偿结果:电力系统功率因素从0.8～0.85提高到0.98～1;电压总谐波畸变率小于4.0%,奇次谐波畸变率小于3.0%,偶次谐波电压畸变率小于1.5%;各次谐波电流大大减少,电能质量得到很大改善。
For problems of voltage and current distortion and capacity waste of grid caused by harmonic pollution,power quality testing and analysis were given,and a scheme of using SVG for harmonic elimination and reactive power compensation were proposed combined with the actual situation of Yaoqiao Coal Mine of Shanghai Datun Energy Co.,Ltd..Results of harmonic elimination and reactive power compensation： power factor raised from 0.8～0.85 to 0.98～1;total harmonic distortion of voltage was less than 4.0%,odd harmonic distortion was less than 3.0%,even harmonic voltage distortion was less than 1.5%;harmonic current was greatly reduced and power quality was greatly improved.
