Electric Power System Monitoring Using High-Frequency Signals

摘要

A system for monitoring an electric power delivery system by obtaining high-frequency electric power system measurements and displaying event information is disclosed herein. The system may use the high-frequency electric power system information to detect traveling waves. The system may generate a display showing fault location on the electric power system, and timing of traveling waves received at locations on the electric power system. The display may include time on one axis and location on another axis. The display may include a waterfall display.

1. A system configured to monitor an electric power delivery system by gathering high-frequency electric power system measurements therefrom, the system comprising:
a data acquisition module configured to receive:
a first plurality of high-frequency electric power system measurements from a local terminal;a second plurality of high-frequency electric power system measurements from a remote terminal; a correlation module configured to time-align the first plurality and the second plurality of high-frequency electric power system measurements; an analysis subsystem configured to identify a location of a high-frequency signal source based on the time-aligned first plurality and the second plurality of high-frequency electric power system measurements; and a visualization subsystem configured to generate a representation of the time-aligned first plurality and the second plurality of high-frequency electric power system measurements and the location of the high-frequency signal source.
