This study introduces a method for voltage sag source location based on Hilbert Huang transformed
monitored current signal. Unlike the traditional method, the proposed method first transforms the recorded current
during the sag event to obtain frequency-time plot (Hilbert spectra) and IMF plot before the location of voltage sag
source is determined. Then based on the change in frequency and IMF the relative location of voltage sag source is
obtained. The effectiveness of the proposed method has been verified through simulation on 20 bus system and by
comparing with an existing S-Transform based method. The results show that the presented method can determine
the location of voltage sag source correctly.
Key words: Hilbert Huang transform, power quality, signal processing, voltage sags, , ,
