大化水电站发电机的增容改造

Modification of Capacity Increment for Generator of Dahua Hydropower Station

大化水电站通过更换发电机定子铁芯和线圈并配合水轮机增容实现机组增容改造。改造后的定子采用了新结构、新工艺。在额定转速、额定电压和额定功率因数不变的条件下 ,发电机的额定出力由原来的 10 0MW提高至 114MW。

WT5BZ]Modification of capacity increment for generating set of Dahua hydropower station achieved by replacing core, coil of stator and increasing the turbine capacity. The new structure and new technique had been apllied to the new stator. And the rated output of generator would be increased from 100 MW to 114 MW under the condition that rated speed, rated voltage and rated power factor were not changed.
