【 摘 要 】

Based on the port energy structure and transient energy function, this paper proposed the generator energy transfer function (GETF) of generator port to analysis power system transient stability issue. By calculating the energy transferred between generators, generator port energy and its changing rate, it can quickly identify the critical generator cluster in a short time after the fault cleared and assess transient stability of the power system, also take control measure. Finally, this method was verified through IEEE-140 node system and it proved the effectiveness of the method.
