摘　　要：为解决现有水库群汛限水位控制系统控制难度大、效率低、控制系统复杂的特点,结合区域的实时雨量预报和水库群的防洪库容信息,提出基于降雨预测及库容补偿的水库群水位动态调节的逐次补偿调度模型。模型主要由天气预报的雨量预测单元、库容补偿的调度补偿单元、洪限水位的调节控制单元和单元间变量的协调单元等组成。主要采用基于逐步逼近的贝尔曼思想,以多次的迭代计算求得理想的汛限水位的动态控制方案。将控制方案运用在潘家口水库群中的结果表明,该方案在保证防控控制调节的基础上可有效提高洪水资源的利用效率,提高发电效益。The current system used to control the maximum water level height of the reservoir has several disadvantages,but the low working efficiency and the shortcomings of the poor control system. This paper designs a successive compensation scheduling model based on the dynamic adjustment of reservoir water level and rainfall prediction based on the reservoir capacity compensation,using the flood control capacity information of the reservoir group and the real time rainfall forecast in the region. The model mainly consists of rainfall forecasting unit of weather forecast,dispatching compensation unit of reservoir capacity compensation,adjustment and control unit of flood limit water level and coordination unit of inter-unit variables. The dynamic control scheme of ideal signal limit water level is obtained through iterative calculation based on the Berman’s idea of step-by-step approximation. The results of complex application of the control scheme in Panjiakou reservoir groups show that the scheme can effectively improve the utilization efficiency of flood resources and increase the power generation efficiency on the basis of ensuring control and control regulation.
