摘要：

Transient stability assessment generally relies on angle-based approaches, which predict out-of-step often too late to maintain power system stability, and need commonly generator's rotor angles measured with a specially deployed optical or magnetic sensor. This study proposed the transient stability index consist of products of post-disturbance voltage fluctuations and their differentiations, instead of rotor angles. In addition, this study provided the theoretical explanation that the proposed index is related to transient stability, and simulated the efficiency of the index in a one/two-machine infinite bus power system model.
