Method, device and computer storage medium for controlling an air compressor of an air compressor station

Abstract

The present disclosure relates to a method, a computing device and a computer storage medium for controlling an air compressor of an air compressor station. The method includes: at the computing device, acquiring the operating power data and start-stop data of multiple air compressors in the air compressor station associated with the sampling time, as well as the air flow data, pressure data and temperature data at the main pipe; Pressure change data at the main pipe; calculate the gas production of the main pipe; determine the single-unit gas production of each air compressor; based on the single-machine gas production and start-stop data of each air compressor, and the pressure change at the main pipe Data and temperature data, the gas production of the main pipe, through the trained prediction model, predict the difference between the gas consumption and the gas production of the main pipe; and based on the predicted difference and the single-machine gas production of each air compressor, Determine the target air compressor to be adjusted so as to control the target air compressor. The present disclosure can reduce pressure and flow fluctuations caused by changes in operating conditions.

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 of air compressor stations. 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 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 compression, and finally achieving the goal of energy saving, is the control system in meeting normal production needs Issues that need to be addressed under the premise. [0003] The traditional solution for controlling the air co...

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] In summary, the traditional scheme for controlling the air compressor of the air compressor station has large fluctuations in pressure and flow due to the adjustment of control parameters, and it is difficult to maintain a stable range
