Enhancements to the Hilbert–Huang Transform for Application to Power System Oscillations

Part of the Power Electronics and Power Systems book series (PEPS)


The Hilbert–Huang transform is introduced for time–frequency analysis of oscillatory signals representing power system dynamic behavior. Fundamental assumptions of the Hilbert–Huang transform are revisited, particularly the ability of empirical mode decomposition to yield monocomponent intrinsic mode functions. In the context of the specific application, some enhancements to the original algorithms are discussed. A wide variety of application examples are employed to demonstrate the efficacy of the improved Hilbert–Huang transform.
