BREAKER DESIGN FOR POWER SYSTEM RESILIENCY

摘要

An autonomous breaker can apply a current through a high impedance source to a bus coupled to either end of a breaker in order to measure an impedance of the bus. The status of the bus can be determined from the measurement. Based on the determined status, a fault detection procedure can be selected and implemented to determine if a fault exists on the bus. When the fault detection procedure has been implemented and no fault has been detected, the breaker can close, and thus couple the bus to another bus.

主权项

1. A method, comprising:
applying a first current to a first bus coupled to a breaker; measuring a first impedance of the first bus after applying the first current to the first bus; determining if a fault exists on the first bus based, at least in part, on the measured first impedance; and coupling the first bus to a second bus coupled to the breaker when no fault exists on the first bus.
