三峡电站初期运行期调峰能力分析

根据初期运行期三峡水库、电站运行特点及下游航道要求,利用等间距穷举搜索的方法,对不同来水、不同装机情况下电站的调峰能力进行了计算,并利用不恒定流数学模型对推求的调峰幅度所对应的出力过程和下泄流量过程进行演算校验,从而使计算结果更符合工程实际的要求.

Peak Regulation Capacity Analysis for the Three Gorges Hydropower Plant in Initial Operation Stage

Based on the operation characteristics of the Three Gorges reservoir and power station in the initial operation stage and the demand for the down-stream navigation channel, in this paper calculated is the peak regulation capacity of the Three Gorges Hydropower Plant for different inflows and different unit numbers by equal step enumeration searching method. And the corresponding processes of unit power output and outflow are calculated and checked by unsteady flow mathematic model, so that the result meets the demands of the project.
