城市排水管网系统的建模、优化运行与控制方法及应用

Urban drainage is an important national strategy and a critical project of civilian engineering. Due to the high complexity of urban drainage networks, the high level of uncertainty in the operational environment, and the stringent standard of its deployment, it is a huge challenge to meet the necessary requirements of the operational safety, energy-saving, and high-efficiency under any circumstances. Aiming at the imperative demand for the urban drainage, this project is going to research the system optimization & control theories, methods, techniques, and applications for the urban drainage networks. The detailed research includes: by analyzing the characteristics of hydraulics, the network topology evolution, etc., we will propose a data-driven modeling method of hydraulics, and build a dynamic model with uncertain hydraulics properties for the drainage network system; by studying the influence of the current state to the drainage under the gravity flow, we will propose a new concept of current situation for the networked drainage, as well as the current situation estimation methods based on the multi-source information fusion. Moreover, we will discuss a distributed multi-source and heterogeneous information fusion theory for the uncertainty environments; by considering the safety mechanisms for preventing the dirty water overflowing and flooding in the routine and emergent cases, we will put forward control theories, methods and techniques of safety operation under typical hazard situations; by investigating the integrated optimization problem for the system’s energy consumption, the quantity of the overflowed dirty water and the efficiency of the drainage, we will propose the optimization and control theories & methods to promote the safety, energy-saving and efficiency for the urban drainage system. Finally, the proposed theories and methods will be tested based on the real systems’ data, and to go trial operation on the Hangzhou urban drainage networks.
