A method and system for monitoring and controlling a power distribution system is provided. The system includes a plurality of circuit breakers and a plurality of node electronic units. Each node electronic unit is mounted remotely from an associated circuit breaker that is electrically coupled with one of the node electronic units. The system also includes a first digital network, and a first central control unit. The first central control unit and the plurality of node electronic units are communicatively coupled to the first digital network. The method includes receiving digital signals from each node electronic unit at the central control unit, determining an operational state of the power distribution system from the digital signal, and transmitting digital signals to the plurality of node electronic units such that the circuit breakers are operable from the first central control unit.

What is claimed is: 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. 2. A power distribution system in accordance with claim 1 wherein said arbitration algorithm determines to control the circuit breaker based on said local commands from the node electronic unit upon failure to receive said local action block signal from said first central control unit. 3. A power distribution system in accordance with claim 1 wherein said first central control unit can operate said plurality of circuit breakers based on information only from one of said plurality of circuit breakers. 4. A power distribution system in accordance with claim 1 wherein said first central control unit can operate one of said plurality of circuit breakers based on information from one or more of said plurality of circuit breakers. 5. A power distribution system in accordance with claim 1 further comprising a sensor for connecting each of said plurality of circuit breakers to said power source of the power distribution system. 6. A power distribution system in accordance with claim 5, wherein said sensor is selected from the group consisting of: a voltage sensor, a current sensor, and any combination thereof. 7. A power distribution system in accordance with claim 1 wherein said node electronic unit transmits at least one digital signal representative of an operational state to said first central control unit. 8. A power distribution system in accordance with claim 7 wherein said at least one digital signal is a raw operational state data signal. 9. A power distribution system in accordance with claim 1 further comprising a second communication network and a second central control unit. 10. A power distribution system comprising: a first circuit breaker connectable to a power source of the power distribution system; a first node electronic unit in communication with said first circuit breaker, said first node electronics unit being configured to selectively generate a local command for said first circuit breaker; a second circuit breaker connectable to the power source; a second node electronic unit in communication with said second circuit breaker, said second node electronics unit being configured to selectively generate a local command for said second circuit breaker; a central control unit communicatively coupled to said first and second node electronic units so that said central control unit can operate at least an instantaneous overcurrent action of said first circuit breaker and said second circuit breaker; a first command resolution module in said first node electronic unit, said first command resolution module controlling said first circuit breaker based on commands from said central control unit or on said local command from said first node electronic unit, said first command resolution module having an arbitration algorithm to determine whether to control the first circuit breaker based on commands from said central control unit or on said local commands from the first node electronic unit, wherein said arbitration algorithm determines to control the first circuit breaker based on commands from said central control unit upon receipt of a local action block signal from said central control unit; and a second command resolution module in said second node electronic unit, said second command resolution module controlling said second circuit breaker based on commands from said central control unit or on said local command from said second node electronic unit, said second command resolution module having an arbitration algorithm to determine whether to control the second circuit breaker based on commands from said central control unit or on said local commands from the second node electronic unit, wherein said arbitration algorithm determines to control the second circuit breaker based on commands from said central control unit upon receipt of a local action block signal from said central control unit.
