Summary:为降低城镇圩区排涝泵站群日常运行能耗,提出排涝站群总能耗最小的多方案试验选优、圩外河道水位控制去劣的优化运行调度方法。将圩区泵站群分组作为试验因素、每组泵站的开机方案为试验水平,以泵站群总能耗为试验结果开展正交试验,对试验结果应用正交分析得到泵站群若干种优化运行方案序列,选择总能耗最小且满足圩外河道的水位控制要求的方案为最优运行调度方案。以上海市城区某区域为实例,应用优化方法编制了2种潮水过程、4种降水条件下的优化调度预案;在不能利用潮水自排的最不利水文工况下,应用优化调度方案与现行调度方案相比,总电功耗最大可节省12%。通过开展优化调度方案与现行方案的节能效益比较,验证了现行方案的合理性并对现行方案提出了优化建议。一方面可为城镇圩区水行政主管部门优化日常调水预案提供参考,另一方面也为丰富和完善排泵站群优化调度方法的理论研究作了有益尝试。

For guaranteeing flood control security, the drainage pumping stations with large installed capacity were distributed densely at urbanization areas set with embankments. Conducting optimization research on operation scheme under different precipitation conditions lower than drainage standard should effectively decrease energy consumption. The main difficulty of operation scheme optimization of urban drainage pumping stations was that with the increase of pumping station quantity and single station’s installed capacity, the combination number of feasible schemes increased too fast to be difficult to calculate. This paper proposed an optimization method which selected the lowest total energy consumption from multiple schemes with orthogonal test and eliminated unqualified schemes with controlling river water level outside the polder. Using this method, pumping stations in the drainage area were divid
