This paper discusses the performance of critical trajectory method (CTrj) for power system transient stability analysis under various loading settings and heavy fault condition. The method obtains Controlling Unstable Equilibrium Point (CUEP) which is essential for estimation of power system stability margins. The CUEP is computed by applying the CTrjto the(More)
Web-based distance education has attracted attention as what can replace partially, even extensively, conventional methods in university education. When distance education in engineering includes remote experiments, it can provide opportunities to study engineering anywhere and at any time. Scheduling the remote classes that feature remote experiments(More)
This paper presents a new computation method for transient stability analysis for electric power systems. Different from existing methods, a minimization problem is formulated for obtaining critical clearing time (CCT). The method is based on the computation of a trajectory on the stability boundary, which is referred to as critical trajectory in this(More)
