- Abstract
In this paper, a convexity index is proposed to detect the stability in a Single Machine Infinite Bus (SMIB) system. Then the criterion is extended in the multi-machine power system which can be induced to an equivalent SMIB system and a supplementary criterion is proposed. Based on the instability criterion presented, we propose a transient stability detection scheme. At last, enormous simulation in IEEE New England 10-machine 39buses power system verifies the accuracy, reliability and fast detection speed of this detection scheme. The stability of all cases are correctly detected online and most unstable cases can be detected in 0.1s after the removal of fault.
