“…Results show that the performance is comparable with the results reported in the literatures [1], [2], [6], [9], [26]. Hence, the contribution of the present work is the development of a Cross-wavelet transform aided FLDA based method for feature selection and SVM based classification technique, effective for a standalone MPQ disturbance sensing module using general purpose microcontroller.…”

“…It was found that [29] multiple power quality events occur at the same period of time in many cases and the signals are basically superposition of more than one PQ disturbances. There are works on multiple PQ disturbances as reported in [1], [2], [6], [9], and [12]. However, these works do not present a methodology suitable for implementation in a standalone module.…”

“…A RS-based scheme can significantly reduce the attributes while keeping meaningful information intact [25,26] without using prior knowledge. During the rule generation process in rough set theory, the dispensable attributes are removed so that the final decision table can contain only minimal or indispensable attributes in a suboptimal way.…”

“…In past studies, feature selection was either in accordance with the filter method based on the features' statistical characteristics, which made it difficult to analyze the classification ability of the feature combination [13,14], or used the wrapper method combined with the particle swarm optimization [15], genetic algorithm [16], rough set theory [17] or other intelligent algorithms, then according to the classification results chose the optimal or sub-optimal feature subset, but the efficiency of the search algorithm is unsatisfactory. Meanwhile, existing feature selection methods have to select different feature subsets under different noise conditions, and this limits the application possibilities of feature selection methods in practical engineering.…”
