摘 要：本文提出了可在线运行的城市实时优化配水模型平台。该方法通过降阶模型（RM）来提高时间精度，利用遗传算法（GA）实现优化配水。应用RM-GA软件需要管网数据、日尺度的需水数据、实时监测数据、每日耗能数据、水压力数据等。通过降阶模型，利用遗传算法，优化计算确定成本最低的配水方案，将调度信息传递给控制系统，启动整个方案。在每一个计算周期末，根据现场数据更新，模型进行实时滚动修正。这个软件是专为以色列海法市开发的，运行实验表明，利用RM-GA提供的配水方案，在夏季和冬季每月可分别降低8%和10%的配水耗能成本。

Abstract：A method for near-optimal real-time on-line operation of urban water distribution system is presented and demonstrated. It uses a reduced model RM of the network which reproduces its performance over time with high fidelity with optimization by a genetic algorithm GA. The RM-GA software uses network data, forecasted demands for an operational planning time-horizon 24 h ahead, field data from a SCADA on the current status of the network, time-of-day energy cost data, and operator-imposed constraints on tank water levels and demand junctions pressures. The GA looks for the near-least-cost operation plan for the whole time horizon, using the reduced network model, and activates the first hour of the plan through the SCADA. At the end of the hour, the status of the network is updated from field data, the time horizon is rolled ahead by 1 h, and the process repeated. The software was developed for and demonstrated on the distribution system of Haifa. Experiments were conducted, in which the operation which simulates the operators’ set-point operation is compared with that obtained by the RM-GA, and energy cost savings of 8 and 10% were calculated for a summer and winter month, respectively.
