Intelligent solid-state power distribution network based on aircraft and power distribution method

Abstract

The invention relates to an intelligent solid-state power distribution network based on an aircraft. The network is constructed by adopting a three-level power distribution framework, and is composed of a first-level power distribution framework composed of at least three first-level SSU monomer solid-state units not lower than 400A, a second-level power distribution framework composed of at least twelve second-level SSU monomer solid-state units not lower than 50A, a third-level power distribution framework composed of at least three RPDU remote power distribution units with single load channels not lower than 15A, and at least one intelligent control unit. The invention further discloses an intelligent solid-state power distribution method based on the aircraft, and power distribution in a normal power distribution operation state and a network abnormal state is carried out according to the intelligent solid-state power distribution network state. Through the real-time monitoring, real-time control and channel current configuration, current distribution of the whole intelligent solid-state power distribution network is realized, and intelligence is improved; the system weight is reduced, and the reliability is improved.

Description

technical field [0001] The invention relates to the technical field of aviation power distribution systems, in particular to an aircraft-based intelligent solid-state power distribution network and a power distribution method. Background technique [0002] The power distribution network architecture is a critical component of an aircraft. The power distribution network architecture of existing aircraft mostly adopts the combination of contactors, circuit breakers, relays, sensors and bus bars to realize the traditional power distribution network architecture. The reliability of bus bars, the hierarchical complexity of bus bars, and the The weight, reliability and lifespan of traditional devices and sensors have seriously restricted the reliability and security of the power distribution network architecture. [0003] The existing power distribution network architecture of the aircraft can only realize the switching of each power supply of the bus bar, and cannot extend the s...
