| Popis: | The sensitivity values of the critical clearing angle and the operating angle of a generator connected to an infinite bus through a double-circuit transmission line, with respect to the system parameters and operating variables are evaluated. The limiting values of the parameters and variables within which the system can remain stable are identified. The sensitivities of the margin of transient stability with respect to the various parameters and variables are also determined. Finally a probabilistic evaluation of the transient stability margin has been carried out from the deterministic sensitivity values of the transient stability margin. The results show that probabilistic evaluation of the transient stability margin should be carried out because deterministic studies give conservative results. |
