Analysis on Applying Busbar Differential Protection and Arc Protection to Airport Electrical Equipment
In order to improve power supply reliability in airport areas and reduce potential losses,considering the airport operation mode and supply requirements,this work analyzes the application of bus differential protection and arc protec-tion to airport electrical equipment from the perspectives of reliability and economy.It discusses potential methods to a-chieve high supply reliability and avoid the time difference disadvantage of conventional protection.In addition,it assesses feasibility and economic investment of adding busbar protection to existing equipment,facilitating both current demands of technological retrofit and future practice of large airport construction.The output of this work is conducive to formulating best protection scheme for electrical equipment and ensuring stable and safe operation of airports.
