【摘要】：随着部分地区可利用水资源日益紧缺,水库需要承担更多功能,但不同功能间会互相影响和制约,优化水库调度图则是协调水库不同兴利目标之间矛盾的关键。以新安江水电站库区供水工程——千岛湖引水工程为实例,考虑年引水规模9.78亿m~3对新安江水电站造成的影响,通过降低调度图中部分丰水月份的保证出力和在降低出力区内增设供水保证线,最终提出调度图优化研究方案。结果表明:水库按优化调度图运行可减少因引水造成的年发电量损失,并能较好地控制水库水位和下泄流量的变化程度。研究成果可为解决水库发电和其他兴利目标之间的矛盾提供借鉴。
[Abstract]:With the increasing shortage of available water resources in some areas, reservoirs need to undertake more functions, but different functions will affect and restrict each other. Optimizing the plan of reservoir operation is the key to coordinate the contradiction between the different profit objectives of the reservoir. Taking the water supply project of the reservoir area of Xinanjiang Hydropower Station-Qiandao Lake diversion project as an example. Considering the influence of 978 million mm3 of annual diversion on Xinanjiang Hydropower Station, by reducing the guaranteed output of part of the high water month in the dispatching diagram and adding the water supply guarantee line in the area of reducing the output water. The results show that the operation of the reservoir according to the optimal operation diagram can reduce the annual power loss caused by water diversion. The research results can be used for reference to solve the contradiction between reservoir power generation and other beneficial objectives.
