The invention discloses a predictive control method of an air compression station, is applied to an air compressor industry, aims at a joint control scene of the air compression station, and relates to a method for performing predictive control according to actual gas consumption change. The decreasing / increasing tendency of the pressure of a mother tube is influenced by multiple factors during the time of loading / unloading delay, and is an uncertain complicated model; through recent historical data analysis, the pressure difference between a point and a valley value / peak value is calculated and regulated, so that advanced interfere is performed, and the predictive adjustment is carried out; and the pressure of the mother tube is controlled within joint control upper and lower limit pressure, so that on one hand, the risk of too low or too high pressure caused by pressure fluctuation is reduced, on the other hand, the safe margin can be further reduced, the average pressure of the mother tube is reduced, and the energy consumption is further reduced.
Description
technical field [0001] The invention relates to the technical field of the air compressor industry, in particular to a method for predictive control of an air compressor station. Background technique [0002] The air compressors in the air compressor station operate according to the parameters set by their respective controllers, resulting in low equipment loading rate and large pressure fluctuations in the pipe network, resulting in high energy consumption. At present, the main solution is to use the joint control of air compressor stations to increase the loading rate of equipment and reduce the average pressure of the pipe network by coordinating the start-stop and loading and unloading of various equipment, so as to achieve the effect of energy saving. The basic principle is: monitor the pressure of the main pipe in real time, and set the upper and lower limit values of the main pipe pressure. When the pressure of the main pipe is lower than the lower limit, control a ...
