Integrated protection, monitoring, and control system

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.
