The collected data are evaluated in real-time with the main objective to give the transmission operator qualitative information regarding stability margins. In our approach an oscillating systems have been modelled by second order autoregressive system using forgetting approach. The stability margins are proposed to define by poles analysis. The approach is demonstrated using real retrospective voltage data registered in 500 kV power grid.
