Resource Overview
HHT analysis of voltage flicker phenomena in power systems (custom-written code, 100% functional, includes EMD decomposition diagrams) implementing HHT for power system stability assessment
Detailed Documentation
Based on the user-provided code, I conducted HHT analysis of voltage flicker phenomena in power systems. By implementing Empirical Mode Decomposition (EMD) with visualization of decomposition diagrams, I successfully applied the Hilbert-Huang Transform (HHT) for power system stability analysis. The methodology effectively extracts intrinsic mode functions (IMFs) from voltage signals using the sifting process, followed by Hilbert spectral analysis to characterize time-frequency properties of voltage fluctuations. This approach provides valuable insights into voltage flicker phenomena, enabling better understanding of power quality issues through time-frequency localization of disturbance patterns.
