小型水电站增效扩容电气设计问题探讨

Discussion on Electrical Design Problems in Synergistic Expansion of Small Hydropower Station

在小型水电站增效扩容改造中,水轮发电机和电气设备的选型设计是非常重要的部分,但往往没有得到足够地重视。如果发电机和电气设备不能与水轮机增效扩容相适应,将会给电站的安全可靠和经济运行带来隐患,也难以真正达到增效扩容的目的。本文主要针对小型水电站水轮发电机和电气改造设计中应该注意的关键问题进行了探讨。

Abstract： In the work of synergistic expansion and renovation of small hydropower station, the selection and design of hydroelectric generating synergies expansion and electrical equipment belong to very important part, but they often obtain inadequate attention. If the generators and electrical equipment can not adapt to turbine efficiency expansion, potential threat will be given to secure, reliable and economic operation of the power station in the future, and it is also difficult to actually reach the synergistic expansion purposes. This paper discuss the key issues in design of the generator and electrical transformation of small hydropower station.
