摘　　要：谐波是电能质量的5项指标之一,也是目前问题比较多、受用户影响比较大的一项指标。因谐波超标而损坏电器和给电网安全运行带来的事故时有报导,并给电能计量带来误差。本文介绍了淮北发电厂进行电能质量监测的目的和工作开展情况,简要论述了谐波是如何产生的,谐波的出现对电力设备的危害,列出了部分监测数据,并对监测数据进行了分析,提出了防范建议。Harmonic is one of the five indexes of power quality, and is also one index that causes many problems and influeces customers greatly. It is occasionally reported that because of too much harmonic, electric apparatuses are damaged, accidents result in the insecurity of the electric web, and errors in power calculation are caused. This article introduces the purpose for Huaibei Power Plant to monitor power quality and how it goes. Also, the author sheds some light on how the harmonic is caused, the consequences to the electric equipment. By presenting some monitoring data, the author analyses the data and then put forward ways to solve problems.
