Airplane starting power generation system simulation framework and hardware design principle circuit

Abstract

Embodiments of the invention disclose an airplane starting power generation system simulation framework and a hardware design principle circuit. By virtue of the embodiments, performance in starting and power generation working conditions of a real airplane starting power generation system can be simulated; by modifying a control algorithm in a characteristic control model of the starting power generation system, different control strategies can be adjusted, and the parameters of a simulation model of a starting generator also can be adjusted so as to adapt real motors of different parameters,thereby verifying realizability of a direct current starting power generation system with different control strategies and motors of different parameters; furthermore, by virtue of the embodiments, simulation of the starting and power generation characteristics of a permanent magnet synchronous motor also can be performed; and an electrical system of the airplane which adopts a direct current starting power generation framework (a synchronous motor plus a rectifier) can be verified very conveniently, thereby greatly shortening the experiment and verification time of the airplane starting power generation system and lowering cost.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of aviation electrical systems, and in particular to a simulation architecture and hardware design principle circuit of an aircraft starting and generating system. Background technique [0002] The starter generator system is an important part of the aircraft electrical system, including starter generators and starter generator controllers and other equipment. [0003] Traditional aircraft mainly use 115VAC power generation system, B787 generator generator voltage is 230VAC, currently aircraft has not yet adopted 540VDC high-voltage direct current power generation system, as the power consumption of aircraft is increasing, the power density requirements are getting higher and higher. The safety margin requirements are getting higher and higher, and the advantages of the 540VDC high-voltage direct current power generation system will gradually appear. [0004] Regardless of whether it i...

Problems solved by technology

In the stage of experimental demonstration, using real motors for experimental research has two disadvantages: one is that the development cycle is long, and it takes several years for a motor to be designed and manufactured, and it takes a lot of money; the other is that one motor corresponds to one Model, when the aircraft model changes, the original motor is difficult to meet the needs of the experiment
