水库群联合供水方案模拟优化研究

Scheme of Multi-Reservoir Water Supply System Joint Operation Based on Simulation

对于由两个或两个以上水库构成的供水系统,将水库群等效为一个聚合水库,建立联合调度供水模式。通过制定合理的供水调度原则,采用优化水库调度图,根据各库实时可供水量实现供水任务合理分配,模拟水库群联合调度供水过程,得到最优供水方案。将该供水方案应用于某市水库群供水调度中,结果表明:各用水户的供水保证率均高于设计保证率,水库群基本满足该地区的用水需求,验证了所提出的水库群联合调度供水方案的可行性与优越性。

As a water supply system consists of two or more reservoirs, the multi-reservoir is equivalent to an aggregation reservoir and becomes a joint operation pattern of water supply system.By designing the water scheduling rules, the optimal decision of water supply was determined by a piece of combined rule curves based on the aggregation reservoir, and the water supply rational allocation of each reservoir was determined by the immediately available water storage capacity of reservoir.This study simulated the process of joint operation to get the optimal scheme of multi-reservoir water supply system joint operation.The scheme was applied to the water supply system of a city.The simulation results show that the water supply guaranteed rates of each water user are higher than the design guaranteed rate, and the multi-reservoir can meet the demands of water supply in the region, which verifies that the above study about the optimal scheme of multi-reservoir water supply system joint operation based on simulation is feasibility and effective.
