摘要
以某钢厂热连轧项目为背景,在Matlab/Simulink环境下利用其电力电子模型库,建立了三相交交变频同步电机滤波器系统仿真模型。根据仿真结果,分析了交交变频器谐波与变压器不同联结组别对交交变频器交流网侧输入电流的影响,给出有无滤波的网侧电流频谱,为交交变频装置交流网侧谐波治理滤波器设计分析提供了一种方法。
Taking one hot strip mill for background the simulation model of three-phase cycloconverter synchronous motor was established ,which is under Power System Blockset of Matlab/Simulink. The distribution regularity of harmonic was investigated, and the effects of the different transformer connection set on the AC current of the net side. The harmonic spectrums of both the AC current with or without the passive harmonics filter was given. It gives one designing and analysis method of the harmonics filter for the cycloconverter.
