Classification of Voltage Disturbances Based on Mathematical Morphology and Dynamic Time Warping

  • Received Date: 27 Nov 2007

  • A novel algorithm based on the mathematical morphology and the dynamic time warping was proposed for improving the accuracy of voltage disturbance classification.In this algorithm,firstly,a morphological filter is utilized for disturbance signals’ filtering;secondly,feature extraction of the filtered signals is done by a d-q transform;finally,the classification results can be obtained by template matching through a dynamic time warping classifier.A simulation was done in Matlab.The simulation result shows that the proposed algorithm has a classification accuracy of over 84% even in a strong noise environment.
