摘　　要：近年来,随着电力系统非线性负荷的迅猛增加,西安电网电能质量的问题也越来越突出,谐波引起的系统保护误动和电器设备损坏均有发生,对用户的影响也有报道。论述了谐波的产生、谐波对电力设备的影响以及谐波的监测,提出了抑制谐波的几种措施,希望为西安电网进一步提高电能质量提供技术支撑。With the rapid increase of non-linear load in recent years, the problem of power quality in Xi＇an network is obvious as well. System protection maloperation ＆ electric equipment damage resulted from harmonic has occurred and effected the users. The paper demonstrates the production of harmonic, effect of harmonic upon electric equipment and monitoring of harmonic. Several measures have been put forward to suppress harmonic. It is hoped to supply technical support for improving power quality.
