【摘要】 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.更多还原

【Abstract】 According to the water supply system in Nanjing with multi-source complex systems,a mathematic model,whose aim function is the operation costs on first-level,was built and solved by genetic algorithm.By analyzing the optimal results,it shows that water supply capacity and hydraulic pressure of every pump station and hydraulic pressure of pressure points A and B have been optimized greatly after optimization,and variable speed pump station takes into function,hydraulic pressures of water distribution network are smaller and change more peacefully.So this study not only provides a feasible way for first-level optimal operation of multi-source complex system,but also does a good job for second-level optimal operation of pump station.更多还原
