针对南京市多水源复杂供水系统,建立了以运行费用为目标函数的一级优化调度模型,并采用遗传算法对其进行求解.优化调度结果表明:各泵站供水量、供水压力及A,B测压点的压力在满足用户供水要求的情况下得到了优化,调速泵站的调速作用得到了充分发挥,各泵站供水量得到了重新分配,供水压力及管网测压点的压力随之发生了变化,优化后的压力普遍变小且随时间变化较优化前平稳;为多水源供水系统一级优化调度提供了可行方法,并为泵站二级调度创造了条件.
Aiming at the multi-water source complex water supply system in Nanjing, a first-level optimal operation model with operation cost as objective function is established and solved by genetic algorithm. The results of optimal operation show that the water supply, water pressure and A, B The pressure at the pressure measuring point is optimized under the condition of meeting the water supply requirements of the users. The speed governing function of the speed regulating pumping station is fully exerted, the water supply of each pumping station is redistributed, the pressure of water supply and the pressure of the pipe network pressure measuring point The pressure after optimization is generally smaller and the change with time is more stable than before optimization. It provides a feasible method for the first-level optimal operation of multi-water source water supply system and creates the conditions for the second-level scheduling of pumping stations.
