Classification and recognition of power quality multi-disturbance based on S-transform and neural networks
Weilin Wu · Mechanical & Electrical Engineering Magazine · 2007
A classification method which can handle multi-disturbance was presented.Using Fourier transform and S transform,the characteristic vectors of power quality disturbances were obtained.The vectors can be divided to amplitude vectors and spectrum vectors.Based on these vectors,parallel BP neural networks can be trained.The simulation results confirm that this classifier can recognize single disturbance as well as multi-disturbance.
