Description
Summary:The transmission-line fault localization of high-voltage (HV) transmission networks and different medium-voltage (MV) wind farms are implemented using a global time-frequency analysis algorithm, energy-spectrum-based hyperbolic S-transform (HS), to extract the potential power signatures from monitoring non-linear and non-stationary fault signals on HV power utility. An energy concentration algorithm is used to transform each HS coefficient into effective features to quantify various faulty events and reduce recognition algorithms' inputs. Furthermore, the Multiclass classifier processes fault location identification. The simulation results show that the proposed method achieves a high classification rate for considering fault inception angles and fault resistance.
