针对水库水沙联合调度方案评价的复杂性及单一评价方法存在的局限性,以向量夹角和最小为优化目标,提出了基于向量夹角和最小的组合评价方法,并以溪洛渡和向家坝梯级水库为例,将该方法应用于水库水沙联合调度的非劣调度方案评价中。结果表明,组合评价方法的计算结果与各单一方法的计算结果相关程度高,可同时反映方案间的优劣次序及其相对优劣程度,其评价结果符合水沙联合调度的客观规律。
Aiming at the complexity of the evaluation scheme and the limitations of the single evaluation method, aiming at the optimization of the angle and the minimum vector angle, a combined evaluation method based on vector angle and minimum is put forward, and the Xiluodu and Xiangjiaba The cascade reservoir, for example, is applied to the evaluation of non-inferior scheduling schemes for the joint operation of reservoir water and sediment. The results show that the calculation results of the combined evaluation method have a high correlation with the calculation results of each single method, which can simultaneously reflect the order of advantages and disadvantages of the programs and their relative merits, and the evaluation results are in line with the objective law of the joint operation.
