EMD-Based Feature Extraction for Power Quality Disturbance Classification Using Moments

“…Among the main advantages of EMD are the extraction of a reduced number of components in comparison to other techniques and its application to linear and nonlinear signals [31]; hence several works have exploit the EMD features for PQD detection and classification [5,32,33]. For instance, in [34], the merits of EMD technique are explored for PQD classification using S-transform and support vector machines SVM. Various indices such as energy, the spread of the instantaneous temporal energy density and deviation of the instantaneous temporal energy density are computed in order to identify a healthy condition and a line-to-ground or line to line to line faults.…”

Primary and backup fault detection techniques for multi‐terminal HVdc systems: a review

“…Empirical mode decomposition is a highly efficient and accurate technique that processes non‐linear and non‐stationary signals in the time domain. In [104], empirical mode decomposition is utilised for dc fault identification and rectification. This technique requires a network of communication or a phasor measurement unit (PMU).…”

Pole‐to‐ground fault ride through strategy for half‐/full‐bridge hybrid MMC‐based radial multi‐terminal HVDC systems with low‐impedance grounded

“…High-voltage direct-current (HVDC) transmission system is attractive for integrating large-scale renewable energy resources at remote locations [1,2]. Since the voltage source converter (VSC)based HVDC system can inherently perform power flow reversal through current reversal, it is much preferred than the line commutated converter (LCC)-based HVDC system in multiterminal application [3,4].…”
