Abstract
Identifying the fault type and faulted phase prior to protection coordination and restoration of the remaining healthy part of the utility power grid in the presence of railway traction load is an important process to ensure power supply system reliability of the grid-connected traction network. An artificial neural network (ANN) based fault classifier has been proposed. The input features to the classifier are derived from multiple detail coefficients of modal current traveling wave signals using the three-level discrete wavelet transform (DWT) with the Daubechies-6 mother wavelet (db6). The Bayesian regularization backpropagation as a supervised machine learning algorithm performs through more than a thousand fault scenarios. The robustness of the proposed DWT-ANN algorithm is verified by testing with the IEEE 9-bus network connected with the large railway traction system through MATLAB Simulink simulations. The superiority in fault identification performance of the proposed algorithm is evident with the highest accuracy of 100% when compared with similar methods.
