High-Frequency Electric Power System Signal Processing System

摘要

The present disclosure pertains to systems and methods for obtaining and processing high-frequency electric power system measurements for control and monitoring of an electric power system. High-frequency measurements may be used to detect traveling waves and/or to detect faults in the electric power system. In various embodiments, a processing device may receive high-frequency electric power system measurements from each of a local location and a remote location and may process the high-frequency electric power system measurements to identify and locate a fault. The occurrence of and location of a fault and may be used to implement protective actions to remediate identified faults.

主权项

1. A system for monitoring an electric power delivery system by gathering high-frequency electric power system measurements therefrom, comprising:
a communication interface configured to communicate with:
a local intelligent electronic device (“IED”) in electrical communication with a local location of the electric power delivery system and configured to communicate high-frequency electric power system measurements based on electrical conditions at the local location; anda remote IED in electrical communication with a remote location of the electric power system and configured to communicate high-frequency electric power system measurements based on electrical conditions at the remote location; a traveling wave detection subsystem to detect a traveling wave based on the high-frequency electric power system measurements from the local IED and the remote IED; a fault detection subsystem configured to detect a fault based on the traveling wave; and a protective action subsystem configured to implement a protective action based on the fault.
