  • Voltage profile based fault location identification system and method of use
    Patent number: 9274161
    Abstract: The present invention provides a method to ensure that distributed resources of a power distribution system remain connected to the circuitry of the power distribution system when a fault occurs at a distributed resource node to assist in identifying the location of the fault by continuing to inject current from the distributed resources into the distribution system. The system contains multiple power electronics based converters which convert the local direct current (DC) distributed sources (DRs) to the alternating current (AC) of the grid. The converters also provide the capability of limiting the current in the system when a fault occurs. The converters also protect the power distribution system equipment against high fault currents.
