Integrated electrical power distribution system using common building blocks

摘要

An electrical power distribution system includes a data bus, separate from the main aircraft data bus, internal to the aircraft electrical power distribution system and an electric power control unit (EPCU) in communication with the internal data bus. Primary and emergency power distribution subsystems include line replaceable modules (LRM) connected in the aircraft electrical power distribution system as electrical load control units (ELCU), each having a common supervisory control interface in communication with the internal data bus, while a secondary power distribution subsystem includes LRMs connected in the aircraft electrical power distribution system as solid state power control (SSPC) units, each having the common supervisory control interface in communication with the internal data bus. The common supervisory control interfaces all execute a common supervisory control logic for receiving commutation commands from the EPCU and providing status back to the EPCU.
