水轮发电机组增容改造可行性研究分析

Feasibility Study of the Capacity Expansion of Hydro-turbine Generator Units

十三五期间中国将有一批水电站进入老龄化阶段。从水轮机增容改造和发电机增容改造两个方面对老电站增容改造可行性进行了分析,认为水轮发电机组经过水轮机、发电机定子、转子、通风冷却系统改造后,能取得较好的增容改造效果。

During the 13 th Five-year plan period,a large number of hydropower stations in China will enter the ageing stage. The feasibility of the capacity expansion of old hydropower stations are studied from two aspects,the hydro-turbine capacity expansion and the generator capacity expansion. It shows that a satisfied capacity expansion could be achieved by renovations of the hydro-turbine,the generator stator and rotor,and the ventilation cooling system.
