| Abstract: | The dynamic characteristic of static var compensator(SVC) its own greatly influences voltage stability of power system.A dynamic analysis method for voltage stability,which remedies the defect of transfer errors in segmentation method and can provide satisfied calculation accuracy and speed,is proposed.Using the proposed method,the influences of time constant of SVC on voltage stability are analyzed under different instability conditions.Analysis results show that when power system loses stability monotonou... |
