| Abstract: | Firstly,the ventilation test was performed to measure actual air flow of the unit at operation with abnormal temperature.Secondly,the total air flow of the generator and its distribution were calculated by network method.Based on it,the stator temperature field of the generator was calculated by FEM.Lastly,the reasons of abnormal temperature occurred in stator core and stator coils of 150MW air-cooled turbo-generator at operation were analyzed. |
