More-electric aircraft distributed power distribution control framework based on intelligent contactors

Abstract

The invention provides a more-electric aircraft distributed power distribution control framework based on intelligent contactors. The control framework comprises a plurality of intelligent contactors, a communication bus and a distributed power distribution control module. The distributed power distribution control module is connected to the plurality of intelligent contactors through the communication bus. Original ordinary contactors are placed by the intelligent contactors which are provided with detection and control chips and can automatically detect input voltages and currents for automatic protection and update state information to the distributed power distribution control module through the communication bus. The framework solves the problems of complicated lines, low reliability and the like due to a conventional centralized power distribution control framework, and distributed intelligent power distribution control is realized in a communication mode of the bus, so that system lines are simplified and the reliability and the flexibility are improved.

Description

technical field [0001] The invention belongs to the field of aviation electrical systems, and in particular relates to a multi-electric aircraft distributed power distribution control architecture based on an intelligent contactor. Background technique [0002] The traditional power distribution control architecture is centralized control. The busbar power controller BPCU is responsible for the power transfer, voltage and current detection, contactor control, fault reconstruction, etc. of the power distribution network in the entire power distribution system. Due to the increasingly complex structure of the distribution network, the number of loads controlled by the contactor is greatly increased. The number of traditional aircraft loads is about 500, and the number of multi-electric aircraft loads is as high as thousands, so the discrete quantities used for control and state feedback are multiplied. The cross-linking complexity of the load interface increases and the relia...

AI Technical Summary

Problems solved by technology

It can be seen from the traditional power distribution architecture diagram that each contactor needs to provide a relatively large number of discrete interfaces (4-10) to the bus power controller (BPCU), and the specific number must be determined according to the control strategy. The relationship is complicated, which is not conducive to the early scheme design
