摘要
以提高洪水资源利用率为目标,研究利用实时水雨工情及短期雨洪预报等综合信息的汛期库水位实时动态控制方法,即改进的预蓄预泄法.应用实例表明,在不降低水库上下游防洪标准的前提条件下,可使桓仁水库及梯级库群的发电效益明显增加.该综合信息的汛期库水位实时动态控制方法,对北方水资源短缺地区调节性能较高的大型水库(水电站)汛期实时调度,有较好的借鉴意义.
In order to improve flood water utilization rate during flood season,a real-time dynamic operation of reservoir water levels called improved pre-storage pre-discharge method is presented,in which real-time information of flood,rainfall,engineering and short-term flood and rainfall forecast issue is studied synthetically. Through its application to Huanren Reservoir and gradient reservoir group,and compared with the originally designed flood operation of reservoir,the results show that the real-time dynamic operation method based on integrated information can increase hydropower generation without increasing flood risk. The method is feasible and practical,and it can also be applied to other reservoirs,especially to the large-scale reservoir or hydropower station for real-time operation in the water shortage region of North China.
