In this paper, the damping torque contributions of power and speed based stabilizers and the effects of these damping torques on the torsional oscillations of large turbo-generators have been investigated under various operating conditions. The results of these investigations show that, in the case of uncompensated power systems, the power based stabilizers introduce almost no damping in the torsional frequency range while the speed based stabilizers contribute large negative damping torques. However, In the case of series capacitor compensated power systems, both power and speed based stabilizers may contribute negative damping in the frequency range of the torsional oscillations of the turbo-generators under certain operating conditions. However, under different operating conditions, power based stabilizers may also contribute relatively large positive damping in the torsional frequency range. The contribution of positive or negative damping by these stabilizers depends on the series capacitor compensation level, the value of the resistance of the transmission network and on the loading conditions of the system. |
