N2 - In this paper, we develop and employ a methodology for assessing the probabilistic transient stability of a small synchronous generator. For this, we examine the probability distribution of the critical clearing time, the greatest time interval to clear the fault to ensure the stability of the post-fault system, considering that the mechanical power injected on the machine is uncertain. The proposed methodology employs the sensitivity of the critical clearing time with respect to the mechanical power to provide a linear relationship between the two variables and properties of random variables to find the probability distribution of the critical clearing time. Finally, data from Monte Carlo simulations are compared with the results obtained by the proposed methodology, proving its efficiency and accuracy.
