Relay protection sampling can use the FFT algorithm

Relay protection sampling can use the FFT algorithm

The numerical technique used in the relay is primarily based on an adapted fast Fourier transform (FFT) algorithm. In FFT, the number of calculations (multiplications and additions) required to filter out the measuring quantities remains reasonable. Abstract—This paper presents the impact of changes in distance protection algorithm when performing simplifications in certain calculations. This paper presents a new approach for Mho Relay Algorithm in MATLAB based on Fast Fourier Transform Algorithm (FFT) which can estimate exact magnitude of DC offset component and completely eliminates it from operating quantities during faults and also makes use of smoothing window to filter out. Distance relays are among the key components of power systems protection and provide capabilities such as fault.

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.
