摘要
白莲河抽水蓄能电站发电电动机单机容量300MW,为三相、立式、半伞、空冷可逆式同步电机,定子分两瓣运输,定子绕组为整数槽双层叠绕组、4支路并联、Y型连接;转子采用无轴结构,支架为圆盘式整体焊接斜支撑结构;轴承冷却采用自身泵外循环系统。这些都是供货商阿尔斯通公司自身较成熟的技术及结构形式。
The generator-motor of Bailianhe Pumped-storage Power Station is made by Alstom. It is three-phase, vertical, half umbrella, air-cooled reversible synchronous generator-motor with a capacity of 300MW. The stator with an integer-slot double-layered, 4 slip parallel connection and Y-connection winding is divided into two split for fransport. The rotor is no shaft and the bolder is a disc-type overall-welding oblique-support structure. The bearing cooling system is self-pumping circulation.
