摘要
由于大型发电机状态监测的需要,对几种发电机定子绕组温度计算方法及温度模型进行了归纳和评价,分析了各种温度计算方法的特点及应用状况,得出了基于发电机运行参数的温度模型精度较高,且适合发电机定子温度在线监测的结论。
Based on th,. need of condition monitoring of large generator, several calculation methods and thermal models of the temperature of generator stator winding were summarized and evaluated. The characterstics of all kinds of calculation methods and application conditions were analyzed. And it was concluded that the thermal model which based on the generator operation parameters was more precision and appropriate for the temperature on line monitoring of the generator stator winding.
