喜河水电站施工进度优化设计与实践

Optimal Design of Construction Schedule and Practice of Xihe Hydropower Station

由于汉江洪水峰高量大、陡涨陡落,喜河水电站施工规划充分结合宽河床、低水头、大泄量、分三期施工导流的特点,以尽量提前下闸蓄水、首台机组提前发电为基础,通过科学、合理的施工进度优化设计,使电站提前半年并网发电。

The floods of the Hanjiang River have the features of high peak flow with abrupt rise and recessionl the construction plan of Xihe hydropower station would be considered the physical features of wide river course with low water head, large discharge, and construction by stages. In order to make the station put into operation ahead of schedule, namely storing water and generate electricity ahead of schedule, the optimal design of construction schedule was adopted, by which the power station was connected into power grid and generate electricity half year ahead of time.
