要約(英語): In order to prevent blackouts initiated by instabilities, early prediction of the potentially dangerous conditions is essential. This paper presents a novel method to early predict the out-of-step condition after being subjected to a severe disturbance. The proposed technique is based on the product of the post-disturbance voltage magnitudes and their differentiations (VΔV) used as the transient stability index. The novel method is computationally simple and fast compared to the rotor angle based transient stability prediction methods. In addition, the algorithm is transparent and does not require machine learning methods, thus would be more acceptable to the industry.
