TY  - JOUR
AB  - This paper focuses on the refinement of standard  Hilbert–Huang transform (HHT) technique to accurately characterize  time varying, multicomponents interarea 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 are 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 result in superior  frequency and temporal resolution than other approaches  for analyzing complicated nonstationary oscillations.
