Abstract

The invention provides a device, application and method for reducing peak current of an aircraft power supply system. The method can reduce the peak current of the aircraft power supply system while the architecture of the power supply system basically is not changed, the ability of the power supply system to cope with instantaneous loading is improved, therefore, the voltage fluctuation of the power supply system is reduced, the electric energy quality of the power supply system is improved, and the stability and safety of the power supply system are improved. Meanwhile, the method is universal and can be compatible with multiple models for use, the design cost is reduced, and the method has an application value and economic benefits.

Description

technical field [0001] The invention belongs to the field of aviation electrical systems, and in particular relates to a device, application and method for reducing the peak current of an aircraft power supply system. Background technique [0002] The current power supply system is mainly composed of main power generation system, auxiliary power generation system, emergency power generation system, external power supply and battery, which are used to provide AC and DC power that meets the power supply characteristics and capacity requirements for onboard electrical equipment. [0003] In the current aviation power system design, the selection of generator capacity is based on electrical load statistics and capacity analysis. The electrical load operating modes mainly include continuous load, 5-minute load, and 5-second load analysis. Through different load operating modes and power system fault status , so as to obtain the generator rated capacity and overload capacity requi...
