摘　　要：对谐波励磁同步发电机空载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。比较计算结果与实验结果,说明了该方法的正确性。基于该方法,分析了转子磁极极尖部的饱和度对谐波励磁同步发电机谐波空载特性的影响,并得出了一些有用的结论。The no-load electromagnetic field of the synchronous generator by the third harmonic excitation is calculated, 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 magnetic saturation on the third harmonic no-load property of synchronous generators by the third harmonic excitation is analyzed. and some useful conclusions are gained.
