Abstract The hazard of harmonics in the power distribution system is very severe，and the passive filter has widely been applied because of its simple in structure，economic and reliable. In this paper，taking the power distribution system in a certain chemical plant as an example，adopting single tuned filter to eliminate 5th，7th harmonics，the design and calculation process of passive filter are introduced in detail.
Key words Harmonics Passive filter Capacitor Reactor
摘 要 配电系统中谐波危害很大，而无源滤波器由于结构简单、经济可靠得以广泛应用，本文以某化工厂配电系统为例，详细介绍采用单调谐滤波器治理5、7次谐波，无源滤波器各元件的设计计算过程。
关键词 谐波 无源滤波器 电容器 电抗器
