基于多目标优化的城市雨水系统控制策略研究

Research on Control Strategy of Urban Rainwater System Based on Multi-objective Optimization

摘要:

随着社会经济的发展，城市水系统精细化管理水平地提高对排水系统的运行控制提出了更高要求。传统的排水系统运行管理常基于单一性能目标和操作经验确定系统控制策略，而对排水系统的复杂性和多功能性考虑不足。集成随机采样、排水水力模型和非支配遗传算法，构建了多目标下的雨水系统控制策略优化求解算法，以上海市某排水分区为案例开展实证研究，研究成果为城市雨水系统的精细化运行管理提供科学决策方法参考。

Abstract:

With the development of economy and society, the improvement of refined management level of urban water systems has put forward higher requirements for the operation control of drainage systems. The traditional operation management mode of drainage system is often based on a single performance objective, and the operational experience determines the control strategy of the system. There is the insufficient consideration for the complexity and multi-functionality of the drainage system. The random sampling, drainage hydraulic model and non-dominated genetic algorithm are integrated to build a multi-objective optimization algorithm for control strategies of rainwater system. Taking a drainage zone in Shanghai as a case, the empirical research is conducted. The research effects can provide the scientific decision-making methods for the refined operation and management of urban rainwater systems.
