三峡水电站枯水期容量和电量利用的研究

Research on Installed Capacity and Energy Utilization of The Three Gorges Project during Drought Period

考虑长江上游干支流主要水电站水库对三峡枯水期流量的自然提高作用下，确定三峡水电站不同水文年枯水期逐月水流平均出力的时间分布；并在三峡确定的供电范围和电力电量分配方案条件下，通过华中、华东系统的电力电量平衡，研究了二大区系统对三峡电站枯水期电力电量的吸收利用情况；最后根据平衡结果，以充分利用三峡电力电量为原则，提出三峡枯水期电力电量的经济合理分配建议．

This paper firstly determines the Three Gorges' monthly water flow output of dif-ferent hydrological years by using compensative scheduling calculation, taking into consideration of natural enhancement of inflows to the Three Gorges reservoir during drought period due to joint operation of main reservoirs located on the upper reaches of the Yangtze River. Then, under the certain condition of power allocation, utilization of the Three Gorges' installed capacity and generating electricity to East China and Central China grids is carefully studied through power and electricity equilibrium method. At last, a better allocation proposal is raised in terms of mak-ing full use of power output of the Three Gorges power station, according to analysis of the re-sults of equilibrium.
