DETECTION AND CHARACTERIZATION OF VOLTAGE SAG USING WAVELET TRANSFORM
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 4, Issue 10
Abstract
This paper presents a new technique for detecting and characterizing voltage sag in power systems based on wavelet transforms. Using the first detail wavelet coefficients, voltage sag characteristics are extracted. This paper presents a MATLAB simulink model implementing the wavelet transform and the values of characteristics are displayed. For this purpose the wavelet technique is used for detecting starting and ending points of voltage sags by energy coefficient. The method is developed by using the discrete wavelet transform analysis.
