A Survey on Research of Power System Transient Stability Based on Wide-Area Measurement Information

Transient stability is an important issue in power system study to which special attentions are paid.In recent years along with the perfection of wide-area measurement system(WAMS) based on phasor measuring units(PMU) it is possible to acquire dynamic response data of the entire power system,so WAMS provides are new measure for the research on transient stability.In four aspects,i.e.,the improvement of traditional analysis method for transient stability,the research on fast transient stability criteria,prediction of transient stability and control of transient stability,the application status of WAMS in the research on power system transient stability is summarized,and it is pointed out that it is the development trend of the research on transient stability based on wide-area measurement information in the future.
