摘要
Abstract
Time-domain simulation (TDS) for power system transient stability is inefficient and tedious,and it can't provide quantitatively stability margin.This paper proposed a novel TDS termination algorithm based on phase-plane trajectory convexity-concavity.After further analysis of phase-plane trajectory motion characteristics,the transient stability margin is defined based on phase-plane trajectory convexity-concavity.Combined with the traditional time-domain simulation,the stability of following trajectory can be evaluated according to the obtained trajectory information based on the proposed stability margin.The simulation can be terminated if the system is detected to be long-term stable and unstable,otherwise,the simulation should be continued until the termination criterion is satisfied.The proposed algorithm can improve off-line transient stability analysis of practical engineering,its efficiency and validity is verified by simulation results on IEEE 39-bus 10-unit system.关键词
