摘要
为了实时、快速消除电网中谐波信号,设计了一种简单实用的谐波抑制装置,主要包括50 Hz信号的LC滤波电路和变压器两部分,前者滤除电网信号中所含有的50 Hz基波信号,后者用来抵消电网信号中所有的谐波信号,并向负载输出基波信号。仿真结果表明,谐波抑制装置的谐波治理效果很好,能消除电路中所有谐波信号,为负载提供稳定的基波信号。
In order to eliminate the harmonic signal in power grid in real time,a simple and practical harmonic suppression device was designed. The device mainly includes the LC filter circuit for 50 Hz signal and transformer. The former filters out the base wave signal of 50 Hz contained in the power grid signal,the latter is used to offset the harmonic signals contained in the grid signal. The simulation results show that the harmonic suppression effect of device is very good,which can eliminate all harmonic signals in the circuit and provides the stable base signal for load.
