Water plant energy saving method and system based on water supply booster pump station flow closed-loop control

Abstract

The invention discloses a water plant energy-saving method and system based on water supply booster pump station flow closed-loop control. The method comprises the following steps of 1, setting the flow of a booster pump station water supply area to be 0, and carrying out the statistics on the instantaneous flow S1 of a water plant after a tip pipe network is cut off; 2, dividing a day into N water supply interval sections according to the standard that S1 is divided into a time period H1 according to starting of a single variable-frequency constant-pressure water supply pump, a time period H2 according to starting of a two-pump combination and a time period H3 according to of starting a second two-pump combination in a water plant; 3, applying segmentation time in the previous step to water inlet time segmentation of a pump station; 4, calculating the actual water supply total amount S total of the booster pump station according to experience; and 5, taking the maximum flow of water plant pump sets of the N water supply interval sections and the actual flow S1 to calculate the water inlet instantaneous flow of the segmented interval of the booster pump station. The water supply capacity of a water plant water supply pump is utilized to the maximum extent, the water plant water supply pump operates efficiently, and water supply power consumption of the water plant is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of water plant energy-saving control, in particular to a water plant energy-saving method and system based on closed-loop flow control of a water supply booster pump station. Background technique [0002] At present, the country vigorously advocates energy conservation and environmental protection. Energy conservation can effectively reduce energy consumption and material waste, so as to improve the utilization efficiency of energy materials. In the process of water supply in water plants, water supply is realized through frequency conversion pumps, but there is waste of water resources in the process of water supply. As well as the problem that the frequency conversion water pump cannot be adjusted in time, resulting in excessive power consumption of water delivery. At present, water plants usually rely on the control system to control the power of the frequency conversion water pump when dealing with this p...

[0002] At present, the country vigorously advocates energy conservation and environmental protection. Energy conservation can effectively reduce energy consumption and material waste, so as to improve the utilization efficiency of energy materials. In the process of water supply in water plants, water supply is realized through frequency conversion pumps, but there is waste of water resources in the process of water supply. As well as the problem that the frequency conversion water pump cannot be adjusted in time, resulting in excessive power consumption of water delivery. At present, water plants usually rely on the control system to control the power of the frequency conversion water pump when dealing with this problem, but the control technology is unreasonable, which makes the power consumption of water delivery excessive. The problem cannot be solved, and the water plant cannot be operated efficiently, which greatly increases the energy consumption of the water plant
