Airplane power supply system experiment platform device

Abstract

The invention provides an airplane power supply system experiment platform device. The airplane power supply system experiment platform device comprises a motor speed regulation control system, a generator excitation control system, a PC end host computer, an inverter and an aviation storage battery. According to the airplane power supply system experiment platform device, the motor speed regulation control system is utilized to replace an aviation engine system to provide power for rotation of a rotor when an AC generator provides power supply, a DSP speed regulation controller in the motor speed regulation control system is used for adjusting a rotation speed of a permanent-magnet synchronous motor, an excitation current of an excitation winding of the AC generator is controlled through an STM32 excitation controller in the generator excitation control system to make an end voltage outputted by the generator be constant, the PC end host computer is used for controlling and displaying data parameters of two systems, and the inverter is used for converting a 28V DC current into 200V / 115V 400Hz AC current needed by an aviation AC load. Through the airplane power supply system experiment platform device, a verifiable platform is provided for theoretical researches on airplane power supply systems, and great importance to popularization of experiment platforms and research and development of modern airplane power supply systems is realized.

Description

technical field [0001] The invention belongs to the technical field of electrical control, in particular to an experimental platform device for an aircraft power supply system.
