摘　　要：蒙开个地区河库连通工程包含南洞一级泵站、南洞二级泵站和长桥海泵站,研究水泵机组不同运行方式对各泵站运行能耗的影响有助于提升工程运行效益。构建了考虑定速节流运行方式和变频调节运行方式下3座泵站站内机组优化组合模型,运用标准遗传算法、精英保留遗传算法对模型进行求解,考虑变频调节装置成本,分析了改造方案的经济性。结果表明:精英保留遗传算法在求解精度上与标准遗传算法相差较小,但在求解效率上显著优于标准遗传算法,能够更好地求解蒙开个地区河库连通工程的泵站机组优化组合模型;变频调节运行方式的节能效果最为显著,各级泵站在流量范围中段存在高效节能段;当各级泵站大部分时间提水流量低于0.7 m^(3)/s或接近满带流量,无需变频改造;其他情况下改造后各级泵站能快速实现正向收益,经济效益较为明显。研究可为蒙开个地区河库连通工程的泵站节能改造提供参考。The river-reservoir connection project in the“Meng-Kai-Ge Area”consists of the Nandong primary pump station,Nandong secondary pump station,and Changqiaohai pump station.Investigating the impact of different operation modes on the energy consumption of pump stations can enhance the project’s operational efficiency.This study establishes an optimal unit commitment model for the three pumping stations,considering both constant speed throttling operation mode and variable frequency regulation operation mode.The model is solved using the standard genetic algorithm(SGA)and the elite reservation genetic algorithm(EGA).The economic efficiency of the transformation is analyzed,taking into account the cost of the variable frequency regulation device.The research findings demonstrate that EGA exhibits similar accuracy to SGA but surpasses it significantly in terms of efficiency when solving the optimal unit commitment model for the river-reservoir connection project’s pump stations in the“Meng-Kai-Ge Area”.The energy-saving effect of frequency conversion regulation is particularly notable,with all pump stations having a relatively high-efficiency and energy-saving section within the middle range of flow.When the daily water lifting flow of the pump stations at all levels is less than 0.7 m^(3)/s or close to full belt flow,frequency conversion transformation is unnecessary.However,in other cases,the pump stations can quickly realize positive benefits through transformation,highlighting the transformation’s significant advantages.These findings provide valuable insights for energy-saving transformations of pump stations in river-reservoir connection projects in the“Meng-Kai-Ge Area”.
