Method and apparatus for optimized centralized critical control architecture for switchgear and power equipment
First Claim
1. A method of monitoring and controlling a power distribution system, said method comprising:
- transmitting at least one first message from a plurality of node electronic units to a processor over a network, said first message being indicative of a power condition in the power distribution system and/or a condition of a circuit breaker in communication with each of said plurality of node electronic units;
determining an operational state of the power distribution system from said first message; and
transmitting at least one second message from said processor to each of said plurality of node electronics unit such that said circuit breakers are operable by said processor.

Abstract
A method of monitoring and controlling a power distribution system is provided. The power distribution system includes a plurality of circuit breakers, a plurality of node electronic units, and wherein each associated circuit breaker is electrically coupled with each respective node electronic unit. The system also includes at least one digital network, and at least one central control processing unit (CCPU) wherein each CCPU includes a first power system global information set, and each CCPU is communicatively coupled to the plurality of node electronic units. The method includes transmitting at least one digital message from each node electronic unit to each CCPU over a respective network, determining an operational state of the power distribution system from the digital message, and transmitting at least one multicast message from each CCPU to each node electronic unit such that the circuit breakers are operable from each CCPU.

35. A power distribution system comprising:
-
a plurality of circuit breakers;
at least one digital network;
at least one central control processing unit; and
a plurality of node electronic units, each node electronic unit being communicatively coupled to said at least one central control processing unit via said at least one digital network and each node electronic unit being communicatively coupled to an associated circuit breaker of said plurality of circuit breakers so that each node electronic unit transmits a first message to said at least one central control processing unit, wherein said at least one central control processing unit transmits a signal to each node electronic unit to ensure that said first message from all of said plurality of node electronic units represents a synchronized condition of the power distribution system. - View Dependent Claims (36, 37)
