三峡围堰发电供水期运行方式研究

Study on the Operation Mode for the Water Supply Period of Three Gorges Power Generation with the Cofferdam

运用水库调度图方法研究了三峡围堰发电供水期运行方式，研究表明：在三峡围堰发电供水 初期，电站运行在高水位对运行有利；供水期后期(4、 5月)来水量加大，利用水库调节，减少弃水， 充分利用水量发电，可以获得较好的综合效益。

The reservoir scheduling graph is applied to the operation mode study for the water supply period of Three Gorges power generation with the cofferdam. The result shows that, at the beginning of the period, it is favorable for the hydropower station to operate at a high water level, and later （April and May）, by decreasing the abandoned water through reservoir regulation, better profits can be achieved by making the best of abundant incoming water to generate electricity.
