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 specifically relates to a distributed power distribution control framework for multi-electric aircraft based on intelligent contactors. The functions include: realizing distributed management of control, reducing the number of discrete interfaces of the power distribution system, and the system is simple and reliable. Background technique [0002] The traditional power distribution control architecture is centralized control. The bus bar power controller BPCU is responsible for the power transmission of the distribution network, voltage and current detection, contactor control, fault reconstruction, etc. in the entire power distribution system. Due to the increasingly complex structure of the distribution network, the number of loads controlled by contactors has increased significantly. The number of traditional aircraft loads is about 500, and the number of multi-electric aircraft ...
