基于多水源优化运行理论的给水系统规划

Water supply system planning based on optimal operation of multiple water sources

在给水系统规划中,合理确定供水水源的流量和压力具有重要意义。以各工况用水需求为约束,以水源运行费用最小化为目标,构建多水源规划模型,采用进化算法求解多工况时段下各水源的供水压力和供水流量。工程规划实例表明,该方法既满足了多工况时段下的用水需求,又节约了水源运行费用,为供水水源的合理规划和供水设施的进一步设计提供了依据。

Rational determination of water sources＇ supplying pressure and flow is very important for its system planning. A multiple water sources planning model which takes the operation cost as objective function under multiple condition constraints is presented. The evolutionary algorithm is used to solve the planning model. It shows that this method satisfies the consumer demand in multiple operating conditions, saves the operation cost, and provides evidence for water sources planning and water facilities ＇further design through an water supply planning example.
