Design and Implementation of Magnetic Levitation Fan Intercontrol System Based on Modbus Communication
With the increasingly strict environmental protection policies,the power generation enterprises continue to promote the technical upgrading of flue gas desulfurization projects,and the more efficient and energy-saving magnetic levitation blower is gradually replacing the traditional Roots blower.Taking the magnetic levitation fan project of a power plant in Shanxi province as the background,based on the master-slave thread relationship of PLC,HMI,TCMS and human technology cloud,Modbus communication to control three magnetic levitation fans with variable air volume were introduced in this paper.Through the integrated platform of remote monitoring,remote data download and remote control,the intelligent operation and maintenance of equipment were realized,which reduced the impact of manual intervention on the operation of equipment.After 168 h test verification,the power consumption of the magnetic levitation fan system could be saved by 14.5％compared with that of the traditional blowe.
