Abstract
The power systems operation is in current evolution as new technologies are added and influence the dynamics of the system. Increased monitoring of the electric variables to be observed as a way to prevent oscillations and unstable transient effects also yields on the analysis of a lot of data. This paper describes two methodologies for assessment of the angular stability of small signals, using data obtained through measurements. A case with noise on measurement, and another without, will be used for evaluations of the methodologies. An acknowledged computational tool will be used to allow the comparative analysis and the results discussed.
