A new detection method of power quality disturbance signal

TL;DRAbstract

For the detection and location of power quality disturbance signal problem, a disturbance localization algorithm is proposed based on the mean sum of the square of S-transform amplitude, with this method the time of occurrence and duration of the disturbance signal is simulated. Simulation results show that the proposed algorithm is simple and effective, able to accurately analyze the disturbance signal, and the magnitude of voltage perturbation, voltage sag and voltage swell can be estimated.
