Review on Transient Instability Detection Method Based on Convexity and Concavity of Phase Trajectory
摘要
Abstract
The response-based transient stability control technology is a hot issue in real-time transient stability analysis of power sys-tem. It has such advantages as independent of modle and parameters of system,real-time detctction and less calculation. Transient in-stability detection method based on angular velocity-rotor angle trajectory is currently a very active branch of response-based real-time transient stability analysis. Firstly,the theory of this method is introduced,then the problems in application of the method to multi-ma-chine power systems are analyzed and discussed. The simulation results on IEEE-39 bus system show that when this method is applied to multi-machine power system,because of incorrect generator-clustering and the time-varying parameter of the equivalent system,this method will produce incorrect stability detection.关键词
