摘要
随着电力系统中用电设备非线性负载的不断增加,产生了大量的谐波,给电网造成不同程度的污染。论述了谐波产生的原因和其对电网的危害。
A lot of harmonic is produced along with nonlinear load escalation of power--driven equipment in power supply system. Polluting in varying degrees is producde to electric network. The reasons of harmonic generation and harm to the electric network are discussed.
