Abstract
Transient Stability of a power systems is its ability to maintain synchronous operation of machine when subjected to a large disturbance. This paper presents a new methodology for speed-up transient stability evaluation in SIME. SIME is a hybrid direct method including time simulation to enhance flexibility. It is difficult to apply the classical SIME to stable cases. To solve this problem, we propose the improved SIME, applicable to stable cases as well as unstable cases. For more fast screening, a reduced order equivalent generator is used in the first step process
