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. cav_un_auth*0262641 2nd International Conference on Computer and Automation Engineering Singapore 26.02.2010-28.02.2010 SG 2011 JA http://hdl.handle.net/11104/0186713 2010 www cav_un_epca*0345439 Proceedings of the 2nd International Conference on Computer and Automation Engineering 978-1-4244-5585-0 1 4 Singapore IEEE 2010
