水电站防洪预报调度图绘制及应用研究

Plotting Reservoir Flood Operation Chart of Hydropower Station and Its Application

以消峰率最大和调洪末期蓄水位最高为综合目标函数,采用优化方法研究绘制水电站水库防洪预报调度图,通过对优化目标函数增加洪水涨水段和落水段泄流量约束,有效地克服了依调度图调度出现的闸门频繁启闭的问题。在石泉水电站的应用结果表明,改进后的防洪预报调度图调洪过程更为合理,实用化操作程度较高,为水电站实时防洪调度提供了有效指导。

Taking the maximum ratio of flood peak reduction and the maximum reservoir water level in flood-end period as overall objective function, optimization method is applied to plot flood control forecasting chart of hydropower station. The problem of frequent open and close of gate is overcome by adding the discharge constraints in flood rising and failing period to the objective function. An example of Shiquan Hydropower Station shows that an improved operation chart is more reasonable and practical for guiding real-time flood control operation of hydropower station effectively.
