Abstract

This paper focuses on the refinement of standard Hilbert Huang transform (HHT) technique to accurately characterize time varying, multi components inter area oscillations. Several improved masking techniques for Empirical Mode Decomposition (EMD) and a local Hilbert transformer are proposed and a number of issues regarding their use and interpretation are identified. Simulated response data from a complex power system model is used to assess the efficacy of the proposed techniques for capturing the temporal evolution of critical system modes. It is shown that the combination of the proposed methods results in superior frequency and temporal resolution than other approaches for analyzing complicated non-stationary oscillations.
