[0002] With the rapid development of air transportation industry, the performance requirements of aircraft ground support equipment are increasingly improved. The aircraft ground starting equipment is an indispensable key equipment in the airport support system, which is mainly used for providing starting power, power support and system testing for the aircraft. In the traditional ground support process, the aircraft mainly relies on the auxiliary power unit (APU) or external power supply vehicle to complete the starting, but these methods have problems such as high energy consumption, high maintenance cost, serious environmental pollution and the like. In recent years, the International Air Organization has put forward more stringent restrictions on carbon emissions and noise pollution, and at the same time, the rapid response capability, compatibility and intelligent level of the ground equipment have put forward new requirements for the large wide-body passenger aircraft and high-frequency flight operation.

It has obvious shortcomings: first, fuel combustion produces exhaust gas, pollutes the environment, is not environmentally friendly, and the diesel engine noise is large, which affects the airport staff and is contrary to sustainable development; second, the starting response speed is limited, the diesel generator needs to be preheated and reach the rated speed before it can output stable power, the starting preparation time is long (usually several minutes), which affects the ground support efficiency, and the diesel engine is easily affected by environmental factors, and the environmental adaptability is poor; third, the energy efficiency utilization rate and operation cost are large, the low working condition energy waste is serious, the mechanical structure of the diesel engine is complex, and the maintenance cost is large.
