摘要
自并励静态励磁系统具有响应速度快、轴系短、振动小、成本低等特点,目前已成为国内外大型新机组优先选择的主要励磁方式,但自并励静态励磁系统在实际应用中存在谐波污染问题。文中主要分析了自并励静态励磁系统谐波产生机理,从理论和仿真的角度对该系统中产生的谐波特性进行研究,并通过现场测试结果验证理论分析与仿真结果的正确性,最后提出谐波治理意见。
Self-shunt static excitation system（SSSES） for generators has some features,such as fast response,short axle,light vibration and low cost,etc.Nowadays,it becomes main excitation method for new large generator units domestic or abroad.However,harmonic pollution is existed in practical application of SSSES.A detailed analysis on harmonic forming mechanism of SSSES is given in the paper.It analyzes harmonics characteristics of SSSES from the theory and the simulation.Then the results on site test verify the correctness of the theoretical analysis and simulation results.Finally,some suggestions for harmonic suppression are proposed.
