Urban drainage area cooperative scheduling method

Abstract

The invention discloses an urban drainage area cooperative scheduling method, which directly adjusts the running number and the running frequency of water pumps of a pump station by adjusting a liquidlevel control value of a drainage pump station, changes the water yield of the pump station, and realizes active regulation and storage of the pump station. On the premise that the regulation and storage effects of all water storage devices of the drainage system are fully utilized, overflowing pollution of regional sewage is minimized. The method is advantaged in that high intelligence is realized, an optimal pump station water level control value can be provided according to the real-time change condition of the pump station water level, so the starting number and the adjusting frequency ofthe drainage pumps are changed, the water level is changed synchronously, the situation that sewage overflows in a specific area, a remaining water storage system is idle is avoided, and finally, sewage overflow pollution in the area is minimized.

Description

technical field [0001] The invention relates to the technical field of urban drainage systems, in particular to a coordinated scheduling method for urban drainage areas. Background technique [0002] The key to the safe operation of the urban drainage system is to control the operating load of each pumping station in the drainage system, so that the operating load of each pumping station is relatively balanced, so as to avoid the situation that the inflow of individual pumping stations is too high and the inflow of other pumping stations is not enough. In this way, the water level of the drainage system is relatively stable, and the phenomenon of sewage overflow is minimized. Therefore, the coordinated control of the water volume of the drainage system is one of the important links in the safe operation of the drainage system. Since the water volume and water level of the drainage system are closely related, and the water volume is generally not directly detected, the coordi...

Problems solved by technology

[0006] The above two types of water level control methods are commonly used pumping station control methods, but there is an obvious problem. When the drainage load exceeds the design scale, the water volume cannot be adjusted. Once the high load runs for a period of time, the pumping station may be damaged. The water level exceeds the limit, thereby creating an overflow risk for the drainage system
