Embodiment 1

[0064] Taking the dispatching of pumping stations in various regions of Tianjin as an example, the specific operation steps are as follows: First, based on the geographical information system, the terrain, landform, pipeline distribution, and river distribution data of various regions in Tianjin are collected, and the one-dimensional open channel non-steady flow equation algorithm is used. Deduce the motion equations of drainage channels or rivers smaller than the discrete grid scale to form a static database of the drainage network in Tianjin, which includes data such as precipitation data, underlying surface data, and pipe network data; then the topography of the database Geomorphology, pipeline distribution and river channel distribution are analyzed, and the grid area is divided, and the rainfall model, surface object generalization model and drainage pipe network generalization model are successively established.

[0065] Considering the topography and various buildings in...

Abstract

The invention provides a simulation modeling and scheduling method for an urban drainage system. The method comprises the following steps: establishing a drainage network static database based on a geographic information system; carrying out grid region division and constructing an urban drainage system model; introducing an Adam algorithm into the urban drainage system model, repeatedly and iteratively optimizing the calculated value and the monitored value of the urban drainage system model, and correcting the error of the urban drainage system model; obtaining an urban ponding area distribution map and a ponding liquid level condition; constructing a robust optimization scheduling model which takes the minimum sum of the current economic scheduling cost and the adjustment cost under real-time operation as a target; and using a robust optimization scheduling model to obtain a value in the uncertain set to obtain a determined feasible solution, and combining the pump station scheduling index to obtain a final pump station scheduling plan. Precise scheduling of the pump station can be achieved, the error between the theoretical value and the actual measured value of the urban drainage model is corrected, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of urban drainage systems, in particular to simulation modeling and dispatching methods of urban drainage systems. Background technique [0002] The urban drainage system is an engineering facility system that treats and removes urban sewage and rainwater. It is an integral part of urban public facilities. Urban drainage system planning is an integral part of urban overall planning. Urban drainage systems usually consist of drainage pipes and sewage treatment plants. The urban drainage system is called one of the "urban lifeline systems". It is an important symbol to measure the level of urban modernization and the most important infrastructure to ensure the normal operation of urban life. Any link lagging or malfunctioning may lead to the paralysis of the entire system. [0003] my country's urban sewage treatment plants are developing rapidly, and the discharge standards are becoming increasingly stringen...
