Abstract
The invention relates to a fault current detection, isolation and clearing system for use in an integrated power generating and distribution arrangement having multiple generators electrically connected to loads and to a distribution bus through circuit breakers. The system includes a power control logic unit and circuit breaker condition detection units which have their outputs electrically coupled to the power control logic unit. Fault current detection circuits are coupled to the electrical connections of the generating and distribution arrangement and have outputs electrically coupled to the power control logic unit. The power control logic unit has an output which is controllingly electrically connected to the circuit breakers to control the circuit breakers and clear faults from the generating and distribution arrangement as a function of circuit breaker conditions and fault currents detected.
