N2 - This paper assesses the ability of a Transient Stability Index (TSI) to evaluate power systems’ transient stability. The assessment is first accomplished by looking into the TSI’s classification accuracy for identifying stable or unstable cases when different transient stability thresholds are used. Although suitable values for these thresholds have been found, there are still some pitfalls in the use of TSI for stability classification. A new approach for the TSI calculation, called Truncated TSI, is proposed, reducing the index’s time window calculation limits. High accuracy of stability classification has been demonstrated using the proposed approach with appropriate settings of the time window parameters.
