A method for computing the short term flicker severity(Pst) based on EMD and TEO fluctuating feature extraction

Simplified and fast method without considering filter for voltage flicker detection

“…Compared with the square detection method, the energy operator, and Kalman filter, the HHT method has small detection error and high detection stability in the entire voltage flicker band [23]. In the HHT method, the modal function component in the voltage flicker is initially extracted using empirical mode decomposition [24]. Then, the voltage flicker value is calculated using the Hilbert transform to obtain the parameters of the voltage flicker fluctuation component [25,26].…”
