Voltage Sag and swell, power Quality (PQ), Discrete Orthogonal S-Transform (DOST), Time-Frequency Representation (TFR), Fourier series, ANFIS
Nowadays power quality is term widely used in power systems wherein the voltage, current, and phase angle are widely discussed and used. The Time Frequency Representation (TFR) provides a powerful method for identification of the non-stationary of the sig
