摘　　要：There are a lot of large capacity nonlinear loads in power systems in coal mine, such as, hoist supply system fed by power converter and cycloconverter. The harmonics generated by those nonlinear loads are very serious. The model for harmonic analysis of power electronic converter and cycloconverter is established, and a novel method for harmonic analysis is proposed in this paper. The suggested method has advantages of less memory capacity need, fast estimation and high accuracy. The comput-ing results are good agreed with the measuring results. The suggested method is much useful for the harmonic prediction of power system in coal mine.There are a lot of large capacity nonlinear loads in power systems in coal mine, such as, hoist supply system fed by power converter and cycloconverter.
