Power signaling based technique for detecting islanding conditions in electric power distribution systems |
摘要 |
A signaling system for detecting power line discontinuity in a power distribution system having a local power generator in a feeder line employs a signal generator that provides a local generator control signal with a preset protocol continuously and is located in the power distribution system upstream of said local power generator. A power detector terminates the local generator control signal and a signal detector in said feeder line detects the presence of the signal and triggers the shutdown of the local generator when the signal is not detected by the signal detector for a predefined period of time.
