摘要
The present invention provides a system 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 a direct current (DC) signal from the controllable voltage source converter of at least one DC voltage distributed resource into the distribution system and modulating an alternating current (AC) signal on top of the direct current (DC) signal.
