摘　　要：国家水网以智慧调控为手段,调控模型是数字孪生水网模型平台的核心组成。错综复杂的水网是典型大系统,水网调控具有多层次、多尺度、多水源、多用户、多目标、多场景等特点,存在众多难点和挑战。针对水网调控的重点和难点,提出了模型体系构建思路:在分析水网布局结构和管理所属基础上,构建网络组成对象数据库和拓扑结构图,明晰各网络并列、串联、包含关系以及各对象的基础信息和相互关系,并实现数据库与拓扑图的动态映射;空间上,基于大系统分解协调原理分层分区进行分析计算;时间上,按照预测、调控、修正的思路实施不同时间尺度下的滚动决策;强化预演功能,采取机理和数据双驱动模式进行仿真模拟,通过自主学习不断完善模型参数或优化模型结构;分析调控模型体系中各类专业模型的关系和作用,构建基于多指标的调控方案综合评估模型,借鉴现代智能优化算法策略,模拟生成可行方案集,并通过演化迭代实现优化调控。The national water network employs intelligent regulation,with control models serving as a core component of the digital twin water network modeling platform.The intricate water network is a typical large-scale system characterized by multiple levels,scales,sources,users,objectives,and scenarios,presenting numerous challenges.Addressing the key points and difficulties of water network regulation,this paper proposes ideas for constructing a model system.Based on analyzing the layout and management of the water network,a database of network components and a topology diagram are established to clarify the parallel,serial,and inclusive relationships of each network,as well as the basic information and interrelationships of each component,achieving dynamic mapping between the database and topology diagram.Spatially,analysis and calculations are conducted hierarchically and partitioned based on the principle of decomposition and coordination of large-scale systems.Temporally,rolling decision-making at different time scales is implemented following the approach of prediction,regulation,and correction.The preview function is enhanced by adopting a dual mechanism and data-driven mode for simulation,continuously improving model parameters or optimizing model structures through autonomous learning.By analyzing the relationships and roles of various specialized models in the control model system,a comprehensive evaluation model of control schemes based on multiple indicators is constructed.Drawing on strategies from modern intelligent optimization algorithms,a set of feasible schemes is simulated and optimized through evolutionary iteration.
