摘　　要：文献［１］对双Ｙ移３０°绕组交流励磁机的四种运行方式的特性进行了分析。在此基础上本文进一步用富里叶级数对双Ｙ移３０°绕组交流励磁机的电压和电流波形进行谐波分析。根据位移角和换相角及电机参数，可以计算双Ｙ移３０°绕组交流励磁机的电压和电流波形以及整流输出特性。并将理论计算和实验结果进行了对照。结果表明，双Ｙ移３０°绕组的交流励磁机比不移相时具有较好的性能。该成果已在生产中应用。On base of the characteristics of a doubel star generator with rectifier Load studied in Reference [1],harmonic performance analysis of double star AC exciters has been completed in this paper.Output characteristics and waves of voltages and currents of the doubel star AC exciter can be calculated.Theoretic results are compared with experimental results obtained from a Laboratory machine.It shows that the double star AC exciter shifted by 30 electrical degrees has better performance and has been adopted by industry.
