摘　　要：利用ANSYS有限元软件自带的APDL编程语言进行二次开发,用二次开发软件对谐波励磁同步发电机空载谐波磁场进行大量有限元计算,应用齿磁通法对电磁场的计算结果进行后处理,得出了谐波绕组空载特性曲线,计算结果与实验结果的比较说明了该方法的正确性。基于该方法,详细分析了阻尼绕组对谐波励磁同步发电机谐波空载特性的影响。The secondly developed software with APDL language of ANSYS is used for the calculation of the no-load electromagnetic field of synchronous generator by the third harmonic excitation, By dealing with the calculation result of the electromagnetic field through tooth flux method, the no-load characteristics curve of the harmonic winding is obtained, the validation of this method are verified by the comparison of the calculation results and the experiment results on.a third harmonic excitation synchronous generator. Based on the method, the effect of damper windings on the no-load property of synchronous generators by the third harmonic excitation is anaylsed.
