Secondary water supply booster pump station energy saving method based on network large closed loop control system

Abstract

The invention discloses a secondary water supply booster pump station energy saving method based on a network large closed loop control system, and belongs to the technical field of information. The method includes the steps of selecting three unfavorable points by reasonably selecting water supply area pressure unfavorable points as feedback of closed loop control and taking system redundancy into consideration, enabling one of the three unfavorable points to participate in the closed loop control feedback, and enabling the other two of the unfavorable points to be used for auxiliary monitoring, wherein unfavorable points need to be selected again to participate in the closed loop control when the pressure values of the unfavorable points are lower than a pressure control value and exceed a certain set threshold value. When wireless network faults occur and data are lost, unfavorable points also need to be selected again to participate in the closed loop control. The PID algorithm is adopted for the whole closed loop control algorithm. Through the method, a user can conduct energy conservation transformation on a secondary water supply booster pump station to obtain large economic benefit.

Description

technical field

[0001] The invention belongs to the field of information technology, and relates to an energy-saving method for a secondary water supply pressurized pumping station based on a network large closed-loop control system. Background technique

[0002] Energy is an important material basis for developing the national economy and improving people's living standards. The secondary water supply pressurization pump station is a large power consumer in the water supply system, and reducing the power consumption of the secondary pressurization pump station is one of the goals pursued by water supply companies. In recent years, water supply enterprises have achieved good results in energy saving of secondary water supply pressurized pump stations and improvement of pump station efficiency. However, due to the large volume, wide area, and fast development of water supply pump stations, there are still unreasonable phenomena in the planning, design, operation and manageme...
