Regional pump station optimization site selection method serving large-scale reconstruction and extension water supply pipe network

Abstract

The invention discloses a regional pump station optimization site selection method serving a large-scale reorganization and expansion water supply pipe network. The method comprises the following steps: (1) selecting a relatively large water supply working condition or an average water supply working condition as a representative working condition for regional pump station optimization site selection; (2) equally dividing a water supply area into N pre-selected areas, carrying out hydraulic adjustment on an original pipe network, calculating the average pressure of nodes of each area, carrying out normalization processing, sorting from small to large, and taking the first m areas as initial site selection areas when m pump stations are arranged; (3) formulating an upstream and downstream candidate node selection mode to form an upstream main pipe node candidate set; (4) setting a plurality of groups of different booster pump station quantity conditions, establishing a water supply network regional pump station optimization site selection model, and solving a regional pump station optimization site selection scheme under the different booster pump station quantity conditions by using an artificial bee colony algorithm; and (5) comparing the optimal solutions under the condition of different numbers of booster pump stations to obtain the number and the distribution mode of the pump stations in the optimal area of the current pipe network.

Description

technical field [0001] The invention belongs to the field of site selection for regional pumping stations of urban water supply pipe networks, in particular to a method for optimal site selection of regional pumping stations serving large-scale reconstruction and expansion of water supply pipe networks. Background technique [0002] The regional pressurized pump station is connected between the water plant and the user, so that the situation of insufficient water pressure in some areas can be improved, and it is an important link in the water supply system. In the process of urban-rural integrated water supply transformation, the number and location of regional booster pump stations have an important impact on the safety and economy of the water supply network. [0003] At present, most of the researches on regional pressurized pumping stations are aimed at the optimal scheduling of pumping stations, and there are few studies on the optimization of the number and location of...

Problems solved by technology

Some scholars also took the minimum construction cost and annual operation management cost of the pumping station as the objective function, and constructed a pressurized pumping station location layout model suitable for the water supply network in the riverside and mountainous areas. The effect is good, but the macro hydraulic model is used, and there are hydraulic errors.
