New Wigner--Ville Spectra Method Improves Power Grid Anomaly Detection

By PulseAugur Editorial · [1 sources] ·

A new research paper proposes using Wigner--Ville Distribution Slice (WVDS) spectra for anomaly detection in power grids. This method analyzes voltage waveforms in real-time, aiming to identify disturbances as they occur. The WVDS approach, when combined with a baseline-normalized deviation score, demonstrated a lower false-alarm rate compared to traditional Fast Fourier Transform (FFT) methods, reducing pre-onset false alarms to 0.69%. While WVDS was more selective, it also missed more anomalies than FFT. AI

    Early Anomaly-Onset Detection based on Wigner--Ville Distribution Slice Spectra: A Transmission-Grid Test Case

    arXiv:2606.15856v1 Announce Type: cross Abstract: Operational disturbance monitoring in power networks requires decisions to be made from waveform windows as they arrive, rather than from completed records after the event. This study evaluates full-vector Wigner--Ville Distributi…
