Method, apparatus and medium for controlling an air compressor in an air compressor station

Abstract

Embodiments of the present disclosure relate to a method, apparatus and medium for controlling an air compressor in an air compressor station. The method includes: acquiring the instantaneous flow rate of the air compressor station based on the sampling time; determining the relationship between the instantaneous flow rate and time of the air compressor station based on the sampling time and the acquired instantaneous flow rate; based on the determined relationship , determine one or more index values ​​of the air compressor station flow during one or more time windows; determine the time period during which the air compressor station flow remains stable based on the determined one or more index values; During the period of time, the combination of air compressors in the air compressor station is adjusted so that the air production volume of the air compressors in the air compressor station matches the gas consumption. In this way, the "active control" of the air compressor station can be realized, so that based on the characteristics of gas demand, the air compressor can be combined in an optimal way to supply air, reducing the pressure fluctuation of the pipe network, so as to achieve the purpose of energy saving.

Description

technical field [0001] The present disclosure relates generally to the control of air compressors, and in particular, to methods, computing devices, and computer storage media for controlling air compressors in an air compressor station. Background technique [0002] Air compressors (referred to as "air compressors") are used to provide air source power and are the core equipment of pneumatic systems. At present, air compressors have been widely used in various industries and have become one of the core devices in related enterprise equipment. Based on environmental protection The demand for energy saving, in the control system of the air compressor, how to minimize unnecessary waste, such as ensuring stable inlet and outlet pressure, stable flow during the compression process, and ultimately achieving the purpose of energy saving, is the control system to meet the normal production needs. Problems that need to be addressed under the premise. [0003] The traditional soluti...

Problems solved by technology

Although the control scheme based on PID control technology has the advantages of simple principle and strong robustness, since the PID control technology calculates the deviation between the actual output and the target given value based on the output of the current feedback, and then uses a specific method to control Therefore, there is a certain delay in the adjustment command, and the target given value of the air compressor is usually not constant, for example, it will change according to the change of working conditions, so it is easy to cause the output pressure and flow of the air compressor to fluctuate. The fluctuation is relatively large, and it is difficult to maintain a stable state

[0004] To sum up, the traditional scheme for controlling the air compressor station has the problem that the air compressor can only be passively controlled according to the feedback of the dynamic pipe network pressure fluctuation
