18脉冲自耦变压整流器分析及不对称输入仿真

Analysis on 18-Pulse Autotransformer Rectifier and Simulation in Asymmetric Put in Voltage

分析了不对称18脉冲ATRU的工作原理和输入输出电流的基本特性。针对三相电源输入不对称对变压整流器的影响进行仿真,并完成样机的基本特性实验、三相不对称实验和实验数据分析。

This topic fully takes analysis of the working principle of asymmetric 18-pulse Auto-Transformer Rectifier Utility （ATRU） and its basic characteristics like input current,output voltage and so on. It takes though imitation and analysis on the existing problem of asymmetric three-phase power supply and possible fault circuits through SABER. Then it completes experiments on model machine＇s basic characteristics and on asymmetry three-phase power input,then analyzes its results.
