Airport ground power supply system

The invention provides an airport ground power supply system, which is provided with a direct current bus, a multi-source input module, a multi-path output electric energy conversion module and a control module, the multi-source input module converges a plurality of accessed power supplies to the direct current bus, and the multi-path output electric energy conversion module takes power from the direct current bus. And the control module can preferentially take power from the power supply with the high priority and preferentially supply power to the load with the high priority according to the power supply power of the connected power supply, the power supply power of the connected load, the power supply priority of each power supply and the working priority of the negative load. According to the airport ground power supply system, comprehensive power supply and distribution management of multi-power-supply functions and multi-load power utilization can be achieved, the working priority of the loads can be ob
