Monitoring island formation in current network, involves generating current pulses, detecting voltage changes or phase shifts as network reaction and monitoring for sudden magnitude changes

摘要

The method involves generating current pulses, detecting voltage changes or phase shifts as a network reaction to the current pulses and concluding that an uncontrolled island formation has occurred from sudden changes in the magnitudes of these reactions. Automatic measurement pulse synchronization is performed where several devices are operated at one point in the network.
