三峡水轮发电机组和水力发电设备的技术进步

Technical progress of hydraulic turbine generator unit and hydroelectric equipment for the Three Gorges Project

举世瞩目的三峡工程，投资巨大，还本付息的唯一手段是电站的发电收入。三峡机组是电站的心脏，其容量、尺寸举世无双，其技术难度大，制造工艺、安装要求高，机组采购引起剧烈的竞争。通过三峡机组的研究和选择将大大促进世界范围内的水力发电设备的技术进步。

The Three Gorges Project which has attracted worldwide attention, will be a project with an extraordinary investment. The unique source for its repayment of principal with interest is the income of hydropower generation.The generator unit is the heart of the hydropower station of the Three Gorges Project and its capacity and size areunrivaled in the world. And due to its big difficult technologies,high requirements for the manufacturing techniquesand installation, and the sharp competition for the generator unit purchase, the technical progress of the hydroelectric power generating equipment in the world will be greatly promoted.
