摘要: The advance in the wide-area measurement system (WAMS) is driving power to trend of monitoring and control. Prony method usually used for low frequency oscillation online identification. However, identified amplitude phase information not sufficiently used. In this paper, adopted detect occurrence obtain mode observability sites. identify generator grouping shapes. time varying characteristics oscillations are studied. behaviors characters displayed by dynamic visual techniques. Demonstrations on “11.9” Guizhou Power Grid substantiate feasibility validation proposed methods.
