Draft fans of preheaters,grinding mills and bag rooms are the major electrical consumers in the cement plant.As the cement market has become increasingly fierce in recent years,it is necessary to evaluate the energy efficiency of these fans and opti-mize their operating efficiency to save power consumption.These energy-saving optimization can also significantly reduce emissions and the carbon footprint of the entire production process.Existing energy efficiency assessments are mostly implemented using embed-ded sensors,which is costly and takes a long time.This paper designs a non-embedded energy efficiency identification system for ce-ment plant fan systems based on online parameters.Taking a centrifugal fan driven by a permanent magnet synchronous motor as an example,a non-differential disturbance observer is used for the estimation.The system design model is established,the software and hardware are built,and the system is tested.The results show the effectiveness of the energy efficiency identification system in this paper.
