“…x(t) Eee~,t]Ut'V/xo I Various methods have been proposed to break the electromagnetic torque variations to synchronizing and dampingtorquecomponents [6][7][8][9][10][11][12][13][14][15][16][17]. The damping torque component is found to be reIated to the real part a, and the synchronizing torque componenl is related to the imaginary part j (U,.…”

This paper presents an artificial neural network based on-line approach to assess the dynamic stabilityof a single machine connected to an infinite bus system. The proposed approach is based on estimating the synchronizing and damping torque coefficients of the synchronous machine from voltage and power on-line measurements. Test results show that the proposed approach is very encouraging for fast evaluation of the dynamic stability.
