摘要
变频器的大量应用,加重了电网的谐波污染。详细分析了变频器产生谐波的机理及其危害,针对南阳卷烟厂配电系统中因大功率变频器产生的谐波问题,采用有源电力滤波器进行谐波补偿,现场运行结果显示:有源电力滤波器能够较好地补偿变频器产生的谐波。
The applications of inverter aggravate the harmonic pollution of power system. The principle of harmonic occurs and the danger of harmonic are analyzed. For eliminating the harmonic issue that caused by inverters of NanYang tobacco plant, active power filter （APF） is used to compensate the harmonic current, the results of operation show that APF could well eliminate the harmonic pollution.
