| 中文摘要: |
| 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 runoff classification method of wet/normal/dry year is not combined with the actual operation process of hydropower stations,which makes it has some limitations in guiding the actual operation of hydropower stations. By taking the Jingsha River cascade hydropower stations as an instance, this paper proposed a new classification method of wet/normal/dry year after the system characteristics analysis of hydropower stations. Its classification results are consistent with the actual operation results,and the consistent rate is as high as 94%,which indicates that the proposed method is reasonable and reliable. Traditional hydrological classification is of static partitioning based on single factor input, while the operation characteristics based classification is the dynamic partitioning based on multi-factor output. The method proposed in this paper can adapt to the complicated actual operation situation, and guide the choice of operation mode more effective for hydropower stations,which has an important practical value. |
