Integrated electrical power distribution system using common building blocks
First Claim
1. An electrical power distribution system comprising:
- a plurality of line replaceable modules (LRMs), the LRMs comprising;
a first LRM connected to a primary power subsystem of the electrical power distribution system and providing electrical load control unit (ELCU) functioning for the first subsystem; and
a second LRM connected to a secondary power subsystem of the electrical power distribution system and providing solid state power control (SSPC) unit functioning for the second subsystem; and
one or more power distribution boxes (PDBs), at least one of the one or more PDBs being configured to distribute primary power, secondary power, and emergency power, and at least one of the one or more PDBs containing at least one of the plurality of LRMs;
wherein the first LRM and the second LRM have identical common supervisory control interface units.

Abstract
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.

19. A method of distributing electrical power in a vehicle having a main data bus, comprising:
-
performing electrical load control unit (ELCU) functioning under supervisory control of an electric power control unit (EPCU) using a standard logic and a standard data format for communication between an ELCU-line replaceable module (ELCU-LRM) and the EPCU; and performing solid state power control (SSPC) functioning under supervisory control of the EPCU using the standard logic and data format for communication between an SSPC-LRM and the EPCU; performing input/output (I/O) function under supervisory control of the EPCU using the standard logic and data format for communication between an I/O LRM and the EPCU; and wherein the communication between the EPCU and the ELCU-LRM and the SSPC-LRM and the I/O LRM uses a power distribution system internal data bus distinct from the vehicle main data bus, wherein the internal data bus is common to the ELCU-LRM, the SSPC-LRM and the I/O LRM. - View Dependent Claims (20)
