Problems solved by technology

[0003] However, in the existing various urban drainage optimization and dispatching systems, the water flow and water level flowing through various pipe networks and manholes can only be estimated by human experience. Therefore, the system cannot predict the generation of floods, pipeline overflow, let alone pass through Scheduling the opening of pumping station units to achieve the purpose of pumping station energy saving

Embodiment Construction

[0056] The method of the present invention will be described in detail below in conjunction with a specific implementation scheme.

[0057] Take the drainage system of a block in a certain city as an example, the system has four pumping stations, each pumping station has several units, each unit has different power, four reservoirs, several drainage manholes, several drainage lines pipeline. In view of the uncertain rainfall in this area, in order to maximize the efficiency of each pumping station and each unit, save energy and reduce consumption, and prevent the water from manholes from overflowing and causing floods, an uncertain hydraulic model of the drainage system must be established. The steps are as follows:

[0058] 1. Based on the basic data of a single node, such as the diameter of the manhole, the upper floor at the bottom, and the upper floor at the top, etc., based on the Saint-Venant hydraulic equation on the one-dimensional free water surface, the implicit fin...

Abstract

The invention includes following parts: building calculation model of hydraulics based on geo information of city pipeline network, description of uncertainty, building uncertainty model of hydraulics, and model modification. Through data structure, system identification, data mining, optimal control of robustness, and predictive control technique of robustness, the invention builds uncertain hydraulics model for urban sewerage and drainage system. Comparing prior art, the invention overcomes disadvantages of empirical estimating throughput of water and water level, and possesses advantages of forecasting generation of city flood effectively, scheduling operation of pumping station in real time so as to save energy.

Description

technical field [0001] The invention belongs to the field of information technology and relates to automation technology, in particular to an uncertain hydraulic model modeling method for urban drainage systems. Background technique [0002] With the rapid development of cities, urban drainage has become one of the bottlenecks restricting the rapid development of cities. Urban drainage is mainly aimed at the existing drainage facilities in the city. Through the drainage system pipe network model and real-time monitoring data, the overall operation of the drainage system is optimized, the overall operation efficiency of the pumping station network is improved, energy saving and consumption reduction, and the city's flood prevention and flood control capabilities are improved. [0003] However, in the existing various urban drainage optimization and dispatching systems, the water flow and water level flowing through various pipe networks and manholes can only be estimated by h...
