Abstract

This invention discloses a method for optimizing the energy efficiency of air compressor equipment based on digital twins, belonging to the field of air compressor equipment technology. The method includes the following steps: collecting real-time current, power, pressure, and flow signals of the air compressor at different load stages; continuously arranging the time series of the collected signals to form a basis for energy change rhythm; and based on this energy change rhythm basis, synchronously analyzing the amplitude fluctuations and phase differences between adjacent signals to identify abnormal segments where energy increases in the opposite direction within a short period. This invention corrects energy consumption misalignment problems through dynamic reference and time rearrangement of the energy change rhythm, establishing a stable correspondence between load changes and energy consumption, and improving the accuracy and reliability of energy efficiency assessment. Simultaneously, by coordinating the adjustment of the pressure output rhythm of the air compressor group, a balanced distribution of energy release on the time axis is achieved, reducing operational fluctuations and start-stop shocks, and enhancing the overall stability and continuity of operation.
