Abstract:
1. A power distribution system comprising: a plurality of circuit breakers connectable to a power source of the power distribution system; a plurality of node electronic units, each node electronic unit of said plurality of node electronic units is in communication with and is configured to generate local commands for a different circuit breaker of said plurality of circuit breakers; a first central control unit communicatively coupled to said plurality of node electronic units by a communications network so that said first central control unit can operate at least an instantaneous overcurrent action of said plurality of circuit breakers; and a command resolution module in each node electronic unit, said command resolution module having an arbitration algorithm to determine whether to control the circuit breaker based on commands from said first central control unit or on said local commands from the node electronic unit, wherein said arbitration algorithm determines to control the circuit breaker based on commands from said first central control unit upon receipt of a local action block signal from said first central control unit.
