中文摘要：
基于汛限水位动态控制预蓄预泄法的基本思想,研究提出了考虑洪水预报信息的水库汛限水位实时动态控制方法,该方法融合了汛限水位动态控制域的上下限值、洪水预报方案可利用的预见期、下游防洪对象的安全泄量等指标值,在实时调度中以允许超蓄水量和实时超蓄水量二者关系来动态判别水库是预蓄还是预泄。以尼尔基水库为例,研究了如何应用基于洪水预报信息的水库汛限水位实时动态控制方法,制定水库汛限水位实时动态控制方案,并进行相应的风险分析及效益计算。实例研究结果表明,此方法制定的汛限水位实时控制方案,不但没有降低原设计防洪标准,而且增加了水库蓄水量与发电效益,可用于指导水库实时调度。
英文摘要：
This paper puts forward a method for real-time dynamic control of the limited water level of reservoir, considering flood forecast information and based on the basic ideas of pre-storage and pre-discharge in dynamic control. This method uses the relationship between real-time over-impoundment storage and permitted over-impoundment to decide reservoir operation mode. Using the method, a control scheme of Nierji reservoir in flood season is obtained. Results show that the scheme improves reservoir benefits without increasing risks and thus can be used in real-time dispatching of reservoirs.
