电能质量 讲座 第五讲 谐波治理

Lecture on Electrical Energy Quality V. Harmonic Suppression

电力系统谐波是影响电力系统安全、经济运行的重要因素之一。如何有效地抑制谐波,保证电力系统的正常运行是广大电力用户亟待解决的问题。阐述了电力系统的谐波治理方法,并对其原理进行了分析。从产生谐波的非线性负荷以及受危害的电力设备和装置两个方面对谐波治理进行了详细介绍。

Harmonic is an important factor which influences the safety operation of power system. How to supress the harmonic and assure the power system run normally are the users need to resolve quickly. The measures and theory of the harmonic suppression were introduced. The harmonic suppression were expounded in detail from two aspects, one is the non-linear load producing the harmonic and another is the electrical equipments to be affected by the harmonic.
