    ABSTRACT
    Transient stability analysis has recently become a major issue in the operation of power systems
    due to the increasing stress on power system networks. This problem requires evaluation of a power
    system's ability to withstand disturbances while maintaining the quality of service. Many different
    techniques have been proposed for transient stability analysis in power systems, specially for a multimachine
    system. These methods include the time domain solutions, the extended equal area criteria,
    and the direct stability methods such as the transient energy function. However, the most methods
    must transform from a multi-machine system to an equivalent machine and infinite bus system [1]-[3],
    [5]-[6]. This paper introduces a method as an accurate algorithm to analyse transient stability for
    power system with an individual machine. It is as a tool to identify stable and unstable conditions of a
    power system after fault clearing with solving differential equations. This method is performed for an
    Northern VietNam power system.
