Transactions on Power Systems Abstract—The fundamental mechanism of transient stability of the conventional power system can be physically understood with the rotor swing dynamics of synchronous generators (SGs). The basic factor affecting the transient stability is the power-angle relationship among the SGs. The integration of a large number of
The problem of defining and classifying power system stability has been addressed by several previous CIGRE and IEEE Task Force reports. These earlier efforts, however, do not completely reflect current industry needs, experiences and understanding. In particular, the definitions are not precise and the classifications do not encompass all practical instability scenarios. This report

Jan 1, 2008· The mechanical–electrical transient of a power system that has experienced a large disturbance can evolve into two different situations. In the first situation, the relative rotor angles among generators exhibit swing (or oscillatory) behavior, but the magnitude of oscillation decays asymptotically; the relative motions among generators eventually disappear, thus the system
To mathematically assess if a system is stable, we derive the swing equation of the power system. In order to determine the transient stability of a power system using swing equation, let us consider a synchronous generator supplied with input shaft power P S producing mechanical torque equal to T S as shown in the figure below.
Most transient stability studies performed today consider at least the generator excitation system, and are therefore actually dynamic studies under the conventional conceptual definition. The previous discussion of transient behaviour of synchronous machines is based on a single machine connected to a good approximation of an infinite bus.
