传统的径流丰平枯划分方法未能结合水库的调节作用,因此在指导水电站水库实际调度时具有一定的局限性。本文以金沙江中游梯级水电站水库优化调度系统为例,通过对系统特征的分析,提出了基于调度特征的水电站水库丰平枯水年划分方法。其划分结果与实际调度结果的一致性高达94%,表明了该方法的可靠性。传统的水文划分是基于输入的单因子、静态划分,而基于调度特征的划分是基于输出的多因子、动态划分,可以适应复杂的实际调度情景,能更有效地指导水电站水库调度模式的选择,具有重要的实用价值。
The traditional method of rainfall subdivision can not combine the regulation of reservoirs, so it has some limitations in guiding the practical dispatching of reservoirs. Taking the reservoir optimal dispatching system of the Cascade Hydropower Station in the middle reaches of the Jinsha River as an example, this paper presents an approach to divide the years of abundance and flatness of hydropower station reservoirs based on the dispatching characteristics by analyzing the system characteristics. The consistency of the results of the partitioning and the actual scheduling is as high as 94%, which shows the reliability of the method. The traditional hydrological division is based on single factor and static division of inputs, while the division based on dispatching characteristics is based on the output of multi-factor and dynamic division, which can adapt to the complicated actual dispatch scenarios and can guide the choice of reservoir dispatching mode more effectively. Has important practical value.
