摘　　要：从二十世纪80年代末开始,水力发电进入了高速发展阶段,水电机组的单机容量从二滩电站的550MW发展到三峡电站的700MW,目前正向1000MW的特大容量机组迈进。本文从对这批巨型混流式水轮发电机组的技术性能的分析入手,探讨巨型水轮发电机组在水力设计、电磁设计、冷却系统及轴承技术等方面的发展趋势。Since the end of 1980s, hydropower goes into the period of high-speed development, unit-powers of hydropower equipments reach 700MW in Three Gorges from 550MW in Ertan, and going up to the target 1000MW of special huge sizes. In this paper, by analyzing technical characteristics of these huge Francis hydroelectric generating units, the developing trends of huge hydroelectric generating units in the aspects of hydraulic design, electromagnetic design, cooling design and thrust bearings technology are discussed.
