Intelligent aircraft secondary power distribution system that facilitates condition based maintenance
First Claim
1. An electrical power distribution system comprising:
- a solid state power controller (SSPC) connected to a power bus which delivers power to one or more SSPC channels;
a load receiving power, the power being controlled by the one or more SSPC channels;
a main data bus in communication with the SSPC via a gateway module; and
a condition based maintenance module in communication with the solid state power controller via a communication network distinct from the main data bus, wherein the communication network is a wireless network.

Abstract
An electrical power distribution system comprises a solid state power controller in communication with an aircraft system main data bus via a gateway module and a condition based maintenance module in communication with the solid state power controller via a communication network distinct from the main data bus. A method of load/feeder health assessment for an electrical power distribution system includes applying a controlled excitation to a load; sampling information from the load/feeder system for the load; characterizing a normal behavior of the load/feeder system for the load; determining if the load characteristics are within the normal behavior profile for the load; and shutting down power to the load if load characteristics are not within the profile when immediate action is indicated or generating a health message for the load when immediate action is not required.

10. An aircraft secondary electrical power distribution system comprising:
-
a solid state power controller (SSPC) that manages power for a load and is in communication with a wireless communication network; one or more SSPC channels of the SSPC receives power from a power bus and delivers controlled power to one or more loads; one or more solid state switching devices (SSSDs) in each of the one or more SSPC channels, each SSSD controlled by an SSSD driver which causes the SSSD to switch power on and off to the one or more loads; a remote sensor in proximity to the load and operable to sense a health condition of the load, wherein the remote sensor is in communication with each channel of the solid state power controller over the wireless communication network; and a condition based maintenance module in communication with the solid state power controller over the wireless communication network. - View Dependent Claims (11, 12, 13)
