Abstract
Abstract The 2.8A to 6.6A power supply method is widely used in Airfield Groud Lighting (AGL) system at present. This power supply method is formulated based on the luminous characteristics of halogen lamps. Although The LED light fixtures significantly reduce the energy consumption of the lamps, the energy-saving effect for the entire AGL system is not ideal, mainly due to the high current of the power supply circuit and the high loss of the circuit itself. Through the classification of low-current AGL system, this article proposes a low-current implementation method suitable for China’s civil aviation. For low-current AGL system, which cannot meet existing civil aviation industry standards and specifications in China’s civil airports, through analyzing the differences between low-current AGL system and existing 6.6A power supply systems in design requirements, implementation and construction, operation and maintenance, as well as existing technical specifications, Propose low Specific requirements for the application of current-assisted AGL system, and propose energy-saving retrofit technical solutions based on the characteristics of AGL projects, laying the foundation for the application of low-current AGL system in Chinese civil airports.
