摘　　要：对交流励磁发电机系统并网运行的主要问题——谐波进行了全面分析。首先建立了交流励磁电机系统并网运行时的精细模型，包括交流励磁电机、交交变频器、转子边外接电抗器、整流变压器、电网内阻抗的影响等。对一台交流励磁发电机实验系统进行了仿真研究和实验对比，分析了该系统并网运行时谐波问题的影响因素。实验与仿真结果的对比证明了模型和分析的正确性。最后指出了减少交流励磁发电机系统并网运行谐波的方法。Research on harmonic of AC excited generator on power systems is carried out. At first a fine mathematic model of AC excited generator on power systems has been presented, considering AC excited generator, cycloconverter, reactor in rotor circuit, rectiformer and power system inductance etc. The factor influencing harmonic of AC excited generator on power systems is analysed. Simulation and experiment on an AC excited generator system are conducted, and the result shows that the model and analysis method presented are effective. The research points out measures of decreasing harmonic of AC excited generator system on power systems.
