Home / Relay protection synchronous sampling
Time‐stamped synchronized measurements represent actual system conditions at any given time and can be utilized in relay protection. Tasks associated with visualizing, storing, and retrieving the phasor measurement data are being worked on by the industry. The advent of satellite-based time-keeping systems and advances in computer technology have made possible protective relay sampling synchronization within 1 μs. Finally, the paper provides power system model test results that demonstrate the ability of the described protective. Relay protection engineers play a vital role in maintaining the stability and safety of electric power grids.
