Intelligent power supply system and method having redundancy and used for direct-current power supplies of large aircraft

Abstract

The invention provides an intelligent power supply system and method having redundancy and used for direct-current power supplies of a large aircraft. The intelligent power supply system comprises anemergency power supply module (100), a main power supply module (200), a ground power supply module (300), an auxiliary power supply module (400), an intelligent power distribution cabinet module (500), an avionics display (600), a control panel (700) and an electrical display control box (800), wherein the emergency power supply module (100), the main power supply module (200), the ground power supply module (300), the auxiliary power supply module (400), the avionics display (600), the control panel (700) and the electrical display control box (800) are respectively connected with the intelligent power distribution cabinet module (500). According to the intelligent power supply system and method having redundancy and used for direct-current power supplies of the large aircraft, intelligent control over grid casting, grid withdrawing and interlocking of various direct-current power supplies of the large aircraft can be achieved, a hard wire logic circuit is effectively simplified, useof conventional contactors and relays is reduced, and therefore, the weight of a primary power distribution system is effectively reduced; and all the key parameters of the power supply system can becollected, displayed and stored, and the state monitoring capability of the power supply system is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of power supplies for aviation electromechanical systems, and relates to the management of switching, de-netting and interlocking of DC power supplies for large aircraft, as well as state acquisition and monitoring, especially as a structure and framework for intelligent uninterrupted power supply of redundant DC power supplies of various types for large aircraft. method. Background technique [0002] The traditional large aircraft DC power supply redundancy power supply system is all realized by conventional power distribution methods. Because the control logic is complex and is realized by hard-wired logic circuits, the control circuit is heavy and very cumbersome, and there are many types and quantities of components. There are many fault points in the electrical control system, and maintenance, fault analysis and troubleshooting are very difficult. [0003] A large-scale rescue / fire-fighting amphibious ...
