(eng): This paper addresses on-line early detection of inter-area electro-mechanical oscillations in power systems using dynamic data such as currents, voltages and angle differences measured across transmission lines in real time. 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.
