Abstract
This paper presents a Bilinear Time Frequency Distribution (BTFD) for recognition and detection of power quality (PQ) disturbances with power related analysis. BTFD have been intensively used to characterize and analyze non stationary signals. The bilinear TFDs offer a good time and frequency resolution and are successfully applied to various reallife problems such as radar, sonar, seismic data analysis, biomedical engineering, and automatic emission [4]. The method used in this paper is Wigner Ville Distribution. This paper will characterize the pattern for the tested power quality disturbances signals such as voltage sag, harmonics, and voltage swell in Time-frequency representation. This proposed BTFD's Time-Frequency Representation has a better insight and time resolution compared to the time domain representation or frequency domain representation alone.
