【摘要】：英那河水库不仅承担着水库上下游的防洪任务,同时作为大连市重要的水源地,其水资源利用效率对于大连市的社会经济发展极其重要,因此水库防洪调度方案的研究具有重要意义。针对英那河水库改扩建后没有适用于目前水库汛期防洪调度的方案问题,通过分析水库产流预报和退水预报的可利用性,并在此基础上,以累积净雨、入库流量和水库水位作为改变水库出库流量的判别指标,研究制定了考虑预报信息的英那河水库防洪调度方案。结果表明:考虑预报信息的英那河水库预报调度方案不仅满足水库调度原则,合理可行,而且便于操作。方案利用退水余量作为水库预泄后回蓄水量,在保证水库兴利效益,提高洪水资源利用效率的同时,还提高了水库的防洪能力。
[Abstract]:Yingnahe Reservoir not only undertakes the task of flood control in the upper and lower reaches of the reservoir, but also serves as an important source of water in Dalian, and its utilization efficiency of water resources is extremely important for the social and economic development of Dalian. Therefore, the study of reservoir flood control operation scheme is of great significance. In view of the problem that Yingnahe Reservoir is not suitable for flood control operation in flood season after reconstruction and extension, this paper analyzes the availability of reservoir runoff prediction and receding water forecast, and on this basis, accumulates the net rain. The inflow discharge and the water level of the reservoir are the discriminant indexes to change the discharge of the reservoir out of the reservoir. The flood control operation scheme of Yingnahe reservoir considering the forecast information is studied. The results show that the forecasting and dispatching scheme of Yingnahe reservoir considering forecast information not only meets the principle of reservoir operation, but also is reasonable and feasible, and is easy to operate. The scheme uses the receding water allowance as the reservoir water storage after pre-discharge, which not only ensures the benefit of the reservoir and improves the efficiency of flood resources utilization, but also improves the flood control capacity of the reservoir.
