    摘要: The present invention provides an electrical power distribution system that includes a first primary distribution panel (PDP) connected to a first source of electrical power and a second PDP connected to a second source of electrical power. The second PDP is connected to the first PDP by a conductor. A first ELCU receives signals corresponding to the flow of current through the first PDP to a load. A second ELCU receiving signals corresponding to the flow of current between the first PDP and the second PDP and a third ELCU receives signals corresponding to the flow of current between the second PDP and the first PDP. The first, second and third ELCUs protect the electrical power distribution system from a variety of fault conditions.

    摘要: On an aircraft, primary power distribution control and secondary power distribution control may be performed with a single line replaceable module (LRM) having an integrated architecture. The LRM may be provided with trip engines that are based on digital signal processors (DSP's). The DSP's may be programmed to allow the trip engines to perform either ELCU functions or SSPC functions. Use of the single LRM precludes a need for complex circuitry that might otherwise be required to coordinate prior-art independent ELCU and SSPC controls.

    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 AC/DC power converter has, as its first stage, a capacitor divider and rectifier and, as the second stage, a switch mode power supply. This configuration may be suitable for low power low voltage aerospace applications. The benefits of the circuit may include small reactive component size; near sinusoidal input current, low EMI emissions resulting from low inrush current; intrinsic current limiting that may eliminate the need for short circuit protection; and low overall component count.

    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.

    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.
