要約(日本語): This paper proposes new techniques for critical trajectory method, a recent new method for obtaining critical clearing time (CCT) for transient stability assessment (TSA). A specific feature of the proposed method lies in its ability to provide exact CCT without approximations since no such methods have existed so far. The method is based on the computation of the critical trajectory, which is defined as the trajectory that starts from a point on a fault-on trajectory at CCT and reaches an end point. It is shown that the proposed methods successfully provide the exact CCT that agrees with the conventional numerical simulation method.
