摘要： A power line communication-based aircraft power distribution system may allow for both power line communication (PLC) technology and spread spectrum time domain reflectometry (SSTDR) technology to be utilized in aircraft power distribution systems to achieve key maintenance functions. Unlike conventional power distribution systems, which may, for example, use only SSTDR for fault detection, the present invention includes a hardware platform that may allow both the PLC and the SSTDR to be utilized in aircraft power distribution systems to achieve key maintenance functions, such as real time wire fault location, and cost and weight savings. Further, unlike conventional power distribution systems, which may only detect and locate damage in feeder conductor wire sections before the power is applied to the load, the power distribution system of the present invention may permit real time wire fault location.

摘要： 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.
