针对水库汛限水位动态控制域的确定为汛限水位动态控制研究的关键问题之一,结合入库流量信息、降雨预报信息等研究确定了水库泄流量分级情况下面临时刻允许控制的库水位值,根据绘制的面临时刻允许库水位值决策支持表,得出水库各级泄流量下的汛限水位动态控制域。实例应用结果表明,该方法考虑了水库汛限水位实时动态控制阶段下游防洪安全允许的各种泄流及其与区间洪水组合的情况,具有较强的可操作性和实用价值,可用于指导水库的实时防洪调度。
According to the research on dynamic control of flood limited water level, one of the key issues in the study of dynamic control of flood limited water level is based on the study of inflow flow information and rainfall forecast information to determine the reservoir water level According to the decision support table of facing the moment of allowable reservoir water level, the dynamic control domain of flood control water level under various discharge levels of reservoir is obtained. The results of practical application show that this method takes into account the various discharges permitted by flood control in the downstream of flood control during the period of flood control water level control and its combination with interval floods. It has strong maneuverability and practical value and can be used to guide reservoirs Real-time flood control scheduling.
