Abstract

The invention discloses method and device for electric load counting and power capacity analysis of an aircraft. The method comprises the following steps of: determining whether a load works or not when the aircraft is in a set working condition according to the working condition of the load; calculating power demand of the load when the load works according to a working mode of the load, power loss distribution, maximum load power and transient power; and accumulating to obtain the power capacity when the aircraft is in the set working condition according to the power demand of each load when the aircraft is in the set working condition. By the method, the electric load of the aircraft is automatically designed, and the counting accuracy and efficiency is improved.

Description

technical field

[0001] The embodiment of the present invention relates to aviation electrical system technology, in particular to a method and device for aircraft electrical load statistics and power supply capacity analysis. Background technique

[0002] Electrical load statistics and power system capacity analysis are indispensable and important links in the design of aircraft electrical systems. The power supply system should meet the capacity requirements of the electrical equipment of the whole machine. Whether the power supply capacity is appropriate will affect the reliability and economy of electrical operation. Therefore, in the design stage of the electrical system, it is necessary to analyze the electrical load and power supply capacity.

[0003] With the advancement of research on more electric aircraft, the number and types of aircraft electrical loads have increased by an order of magnitude compared with traditional aircraft. According to incomplete statistic...
