摘　　要：城市供水泵站运行方式优化调度的关键是建立与其相适应的数学模型以及求解。鉴于我国大中型城市供水泵站正逐步推广非同步调速运行方式的现状,以南京市某供水泵站为例,研究建立了适合非同步调速供水泵站优化调度的数学模型,并采用寻优能力较强的遗传算法对模型进行了求解。优化结果表明,该模型及求解方法合理有效,可适应该泵站的优化调度运行,并充分利用调速泵的调速节能作用,使供水泵站在满足供水要求的前提下降低能耗。The establishment and solution of appropriate mathematical models of pumping stations are very important to the optimal dispatching of urban water-supply pumping stations. Since the asynchronous speed adjusting systems are being generalized in many water-supply pumping stations in medium and large cities in China, taking a pumping station in Nanjing for example, the mathematical model suitable for the optimal dispatching of urban water-supply pumping stations with asynchronous speed adjusting was built and solved by the genetic algorithm which has great capability in optimization. The results show that the model and the solution method are reasonable and effective, and they are adaptable to the optimal dispatching of this water-supply pumping station. Taking full advantage of the speed adjusting and energy saving of speed adjusting pump can reduce energy consumption of water-supply pumping station when the water-supply requirement is met.
