| 摘 要： | 在同步发电机派克方程的基础上,利用同步发电机的空载特性曲线,建立用电压、电流、磁链表示的考虑主磁路交叉饱和的同步发电机数学模型.通过仿真研究论证该模型的正确性,该模型适用于研究同步发电机处于非正常工况等主磁路饱和程度变化较大时的运行行为,能够比较准确地分析主磁路饱和程度变化对于同步发电机运行行为的影响,相比线性模型具有准确性高和适用范围广的优点.

| Abstract: | Based on Park equation of the synchronous generator,a new kind of transient mathematical model on synchronous generators is presented.In the model the saturation of main magnetic circuit is considered by using the no load characteristic curve of the synchronous generator.And the feasibility and accuracy of the model are verified through comparing the results of simulation.When the synchronous generator operates on the nonnormal condition,the model is significantly better than the linear model. |

| Keywords: | synchronous generator Park equation no-load characteristics cross saturation |
