三峡电站水轮机方案设计

Schematic Design for Hydraulic Turbines of Three Gorges Project

叙述三峡水电站的特点和对水轮机的基本要求,介绍东电公司在三峡水轮机方案设计中的设想以及对初期低水头发电,高水头小负荷运行稳定性、抗泥沙磨损性能与制造可行性等重大问题的研究,为设计制造三峡机组打下基础。

This article describes the features of Three Gorges Project and the basic requirements to hydraulic turbines. The article also introduces DFEM's (Dongfang Electrical Machinery Co. , Ltd. ) ideas in the schematic design of Three Gorges hydraulic turbine, as well as DFEM's studies to some important problems including power generation at low head in the initial stage, operation stability with low load at high head, wearability against sediment and manufacturability etc. , which lays the foundation for Three Gorges set.
