摘要
This paper proposes novel techniques for monitoring the oscillatory modes in wide-area using synchrophasors measurements. The oscillatory modes are identified through the Taylor-Kalman-Fourier, Alternating Kalman, and Taylor-Fourier digital filters, accomplishing a ringdown analysis. They are stated multidimensionally in order to process multiple channels from PMU data. The proposals are tested under noisy conditions with simulated data, exhibiting the capability of identifying multiple electromechanical modes, and providing global information about modal properties of the power system.
