Power Quality Disturbances Detection and Classification Rule-Based Decision Tree

In this paper, the power quality (PQ) disturbances have been detected and classified using Stockwell’s transform (S-transform) rule-based decision tree (DT) according to IEEE standards. The proposed technique based on extracted features of PQ events signals, which are from timefrequency analysis. Several considered with simple complex include spike, flicker, oscillatory transient, impulsive notch. performance robustness for recognition demonstrated through results various disturbances. By comparing other reported studies it was distinguished under noiseless noisy conditions
