摘要：
This paper presents the Hybrid method of power system transient stability analysis, which combines the desirable features of both the time domain simulation technique and the direct method of transient stability analysis. The Hybrid method first computes the actual system trajectory using time domain simulation, then evaluates the transient energy function (IEF) in order to derive a stability index for fast derivation of transient stability limits. Proper criteria are proposed in this paper to stop the time domain simulation of system trajectory to reduce CPU time, once the status of the system has been identified. The method was successfully applied to three test systems varying in size from 4 generators to 50 generators. The method is shown to be a potential tool for on line calculation of transient stability (1S) limits. © 1990 IEEE
