摘要
通过对600MW汽轮发电机负序涡流场的有限元计算,以200MW汽轮发电机负序试验的实测数据为基础,采用计算与类比相结合的方法来确定散热系数和负序有效高温点的温度,从而推算出600MW发电机的负序能力,为发电机的设计与运行提供依据。
It is calculated negative sequence eddy field of 600MW turbine generator.With negative sequence capacity test data of 200MW turbine generator,it adopts method of combined calculation with analogy analysis,the coefficient of heat dissipation and the highest temperature are educed,accordingly the 600MW turbine generator negative sequence capacity is calculated,it is proved that this research is very useful for generator design and safe operation.
