大型泵站大多安装有同步电动机组，因此，基本具备倒转发电条件。睢宁二站属于南水北调东线一期工程，由于上下游水位差较大，机组飞逸转速高，因而设计推荐采用同转速倒转发电方案，这种自同期并网发电方式简单、投资少、见效快，缺点是效率相对偏低。通过对泵站水工建筑物、机电设备、水文资料等进行分析研究，初步提出了睢宁二站发电并网的技术方案。

Synchronous motor units are mostly installed in large pumping stations, which are basically ready for reverse genera-tion. Theoretically, due to larger water head and higher runaway speed of units, reverse generation can be achieved in Suining No. 2 Pumping Station, one part of the first stage of the East-route Project of South-to-North Water Diversion. Despite of rel-atively low efficiency, the self-synchronizing way for grid-connected power generation is simpler, cheaper and faster. The pa-per presents the technical scheme for the grid-connected power generation of Suining No. 2 Pumping Station by the analysis of hydraulic structure, electro-mechanical equipment and hydrological data of the pumping station.
