Variance‐Empirical Mode Decomposition Method for Fault Detection in MMC‐HVDC Transmission Lines
Energy Science &Engineering, EarlyView.A variance‐embedded empirical mode decomposition (VEMD) method is proposed for fast and accurate fault detection in MMC‐HVDC transmission lines. By combining variance analysis with EMD, the method reliably detects various faults without communication links and remains robust to noise and non‐fault transients.
