摘　　要：为了提高梯级泵站系统运行效率,节约工程运行成本,以梯级泵站运行效率最大化为目标,建立梯级泵站优化调度模型,提出基于改进哈里斯鹰算法(HUHHO)的梯级泵站优化调度方法.将饥饿率引入哈里斯鹰算法(HHO)以更好地实现探索与开发之间的平衡;在探索阶段添加1个偏移项以考虑哈里斯鹰饥饿感强弱对搜寻猎物能力的影响,提高算法的寻优能力、避免陷入局部最优.通过基准测试函数验证HUHHO寻优性能的优越性.将HUHHO应用于北京市某三级泵站优化调度中,对HUHHO求解梯级泵站优化调度问题的可行性与有效性进行验证.结果表明:相较于现状方案,基于HUHHO的优化方案可使梯级泵站运行效率提高0.11个百分点,年运行成本节约42 187元,优于利用粒子群优化算法(PSO)、遗传算法(GA)、HHO得到的运行效率及节约成本.The optimal operation model of cascade pumping stations was established with the objective function of maximizing the total operation efficiency.An optimized scheduling method based on improved Harris hawks optimization(HUHHO)was proposed to raise the operation efficiency of the system and save the cost.Firstly,the starvation rate was introduced in order to control the balance between exploration and exploitation.Secondly,considering the effect of hunger intensity on prey hunting ability,an offset item was added in the exploration stage to enhance the search capability and avoid falling into the local optimum.Then,the superior performance of HUHHO was demonstrated by the benchmark functions.In addition,the proposed method was applied to the optimal operation of a three-stage pumping station in Beijing.Finally,the feasibility and effectiveness of HUHHO for solving the optimal scheduling problem in cascade pumping stations were verified.Results show that compared with the current scheme,the optimization scheme based on HUHHO can increase the operation efficiency of the system by 0.11 percentage points and save 42187 yuan in annual operating costs,which are better than those obtained by using particle swarm optimization(PSO),genetic algorithm(GA)and Harris hawks optimization(HHO).
