基于调配管理的北京市多水源水量联合调度研究

针对北京市复杂供水系统多水源联合调配与管理,依据最严格水资源管理制度,在规划用水总量控制红线和用水效率控制红线管控下,充分考虑水行政主管部门调配管理目标与约束,绘制了基于水源-工程-单位(水管系统)-用户的多维嵌套北京市供水网络拓扑结构,建立了北京市多水源联合调度模拟模型,实现了用水管控、水源配置、水量调度统筹的多水源联合调度。计算结果表明:2019年全市用水管控39.6亿m~3,考虑输水损失和干流补水后,由本地新水供水20.3亿m~3,利用再生水11.5亿m~3,调用南水北调水9.7亿m~3;在现状工程条件下,为满足城市生活与工业用水和城区重点区域河湖基本生态需求,可充分调配南水北调水约9～10亿m~3;通过加大调水可进一步恢复本地水源储备和改善河湖生态环境。研究成果可为水行政主管部门开展日常水量调配工作提供技术支撑。

Study on allocation management-based joint multi-water source dispatch and managementin Beijing

Aiming at the joint multi-water source dispatch and management of the complicated water supply system in Beijing， the dispatch and management target and constraint of the water administrative department are fully considered under the control of both the control red-line of the planned total water consumption and the control red-line of water-use efficiency based on the most stringent water resources management system，and then the water source-project-unit ( water management system) -user-based multi-dimensional nesting network topological structure for the water supply in Beijing is drawn and the model for simulating the joint multi-water source dispatch in Beijing is established，thus the joint multi-water source dispatch is realized through planning water-use control，water source allocation and water dispatch as a whole. The calculation result shows that the citywide water-use control is to be 3. 96 billion m3 in 2019，while the supply from local new water is to be 2. 03 billion m3 ，the reclaimed water is to be 1. 15 billion m3 and the water from the South-to-North Water Transfer Project is to be 970 million m3 after considering water delivery loss and main stream water supplement. Under the status engineering condition，the water from the South-to-North Water Transfer Project can be fully allocated by 0. 9 ～ 1. 0 billion m3 for satisfying the urban domestic and industrial water uses and meeting the basic ecological demands of rivers and lakes within the key urban areas. Through further enlarging the water transfer scale，the reserve of local water resource can be further restored，and then the eco-environment of river and lake can be improved as well. The study result can provide a technical support for the daily water dispatch made by the water administrative department concerned
