A new method based on elementary catastrophe theory for stability assessment of power systems
基于初等灾变理论的电力系统在线稳定新方法
Abstract : the paper presents a new method to study stability of power systems . it applied bifurcation approach of elementary catastrophe theory to find out control parameters bifurcation values ， which decide stability of power systems , further , stability region can be obtained . in this way , we can assess stability of power systems . the numerical simulation has shown that this method can solve effectively online stability assessment problem of power systems
文摘:提出了一种研究电力系统稳定问题的新方法.它运用初等灾变理论中分岔的概念找出决定电力系统稳定的控制参数的分岔值，从而确定了系统的稳定区域，由稳定区域即可进行系统的稳定判断.数值仿真表明这一方法能有效地解决电力系统在线稳定判断问题
