| Abstract | ||
| This paper presents a brief description of Lyapunov's direct method, and demonstrates its efficiency with respect to previous indirect step by step method, in order to compute the stability of electromechanically power system. The practical advantages of this direct method of analysis are: (i) Rapid solution. (ii) Ability to compute the degree of stability. (iii) For computing the critical clearing time integrate the faulted equation, until V=V1. The basic concepts and the mathematical formulation of the method are summarized. Practical test system are used to demonstrate the superior efficiency of the method relative to step by step method. | ||
