Classification of PQ Disturbances in Induction Motor using Neuro-Fuzzy

Sridhar S, Uma Rao K., Raksha Umesh, Harish K.S


This paper presents a methodology of classification of PQ disturbances in the supply to induction motor using ANFIS. Wavelet transform is applied to the stator currents for the extraction of the signature indicating the variations in the supply. These wavelet coefficients are fed as input to ANFIS. This data has been divided into two sets: 37 training data set and 38 testing data set. The training data set has been used to train different adaptive neuro-fuzzy inference system (ANFIS) models and testing data set has been used to validate the models. The simulation is done using MATLAB/SIMULINK. The proposed network has performance efficiency of 93.34%.



Keywords: Adaptive neuro-fuzzy inference system, discrete wavelet transforms, induction motor, power quality, PQ disturbances
