Abstract


This paper focus on events, that causes a temporary decrease in the magnitude of voltage at power frequency. The paper aims at characterization of voltage sags due to faults and induction motor starting. The modified IEEE distribution system is considered for study and same is simulated using PSCAD. The signals for features extraction are processed using Wavelet transform. The Statistical parameters computed from detailed level 4 (D-4) are used as an input to classifier.  Multilayer perceptron   network is used as a classifier to differentiate the cause behind the voltage sag.
