摘　　要：针对事故停泵水锤防护多目标优化问题,以无量纲最大水锤压力值、泵最小转速、单向调压塔水体积作为控制目标,以调压塔直径、初始水深、安装位置等为决策变量,建立水锤防护的多目标优化数学模型,并采用萤火虫算法(FA)求得Pareto解集,进而利用熵权-理想点法(EW-IPM)计算获得最优防护方案。结果表明,单向调压塔宜布置于局部高点的后缘,在管道局部高点附近增设空气阀后可有效减小单向调压塔体积;单向调压塔径高比、管径比分别宜在0.23~0.29、0.10~0.14之间取值;基于EW-IPM法计算获得Pareto解中的最优方案,采用该方案进行水锤防护,不仅经济成本较低,且能较好地满足水锤防护效果,为事故停泵水锤多目标研究提供了理论支持。In response to the multi-objective optimization problem of water hammer protection during pump shutdown accidents,the dimensionless maximum water hammer pressure value,the minimum pump speed,and the water volume of the unidirectional pressure regulating tower were taken as the control objectives.The decision variables include the diameter of the pressure regulating tower,initial water depth,and installation position.A multi-objective optimization mathematical model for water hammer protection was established,and the Firefly Algorithm(FA)was used to obtain the Pareto solution set.Then,the entropy weight ideal point method(EW-IPM)was used to calculate the optimal protection scheme.The results indicate that the leading edge of the local high point should be arranged for the one-way pressure regulating tower,and adding air valves near the local high point of the pipeline can effectively reduce the volume of the oneway pressure regulating tower;The diameter to height ratio and pipe diameter ratio of the pressure regulating tower should be taken between 0.23-0.29 and 0.10-0.14,respectively;Based on the EW-IPM method,the optimal scheme in Pareto solutions was obtained.This scheme has lower economic cost and can better meet the water hammer protection effect,which provide theoretical support for multi-objective research on water hammer caused by pump shutdown accidents.
