摘要
梯级泵站在流域内或流域间调水,能有效解决水资源时空分布不均的问题,但也消耗大量能源。通过制定合理的运行方案,探讨梯级泵站节能降耗和调控优化策略,以降低系统运行成本,提高工程经济效益和保证运行安全具有重大意义。长输水系统梯级泵站运行优化研究目前主要集中在四个领域,即梯级泵站运行优化目标理论研究、梯级泵站优化问题算法及模型求解、基于变频调速技术的梯级泵站运行优化相关研究和梯级泵站的事故紧急调度相关研究。但对梯级泵站这样庞杂的系统,优化计算方法的效率仍需进一步提高,模型优化求解时应考虑更多影响因素,在梯级泵站运行优化中有压部分的紧急事故调度还需深入研究。
The cascade pumping station transfers water within or between basins,which can effectively solve the problem of uneven spatial and temporal distribution of water resources,but it also consumes a lot of energy.It is of great significance to formulate a reasonable operation plan and to develop an optimization strategy for cascade pumping station in energy saving and consumption reducing in order to reduce the system operation cost,to improve its economic benefit and to ensure the operation safety.At present,researches on operation optimization of cascade pumping stations in long-distance water transmission system mainly focus on four fields,namely,theoretical research on operation optimization objectives,optimization algorithm and model solution,operation optimization based on variable frequency speed regulation technology,and related researches on emergency dispatch of cascade pumping stations.For such a complex system as cascade pumping station,the efficiency of optimization calculation method still needs to be further improved,more influencing factors should be taken into account when solving the model optimization,and the emergency dispatching in pressure part of cascade pumping station needs to be studied more.
