Inter-area oscillation analysis is very important in power system stability research. There are many factors influencing inter-area oscillation. The relationships between various factors and inter-area oscillation are very complex. Most current studies on the relationships are quite limited, without enough theoretical analysis. Using theoretical deduction,(More)
When a large interconnected power system is disturbed by large or small disturbance, its electro-mechanical oscillations become one of the most important factors affecting the system stability. This paper studies the characteristics of electro-mechanical oscillation trajectories with respect to initial conditions decided by disturbances. Influences of the(More)
This paper presents a method to compute unstable equilibrium points on the transient stability boundary of power systems with detailed generator modeling. According to the stability region theory of nonlinear dynamic systems, relations of unstable equilibrium points on different stability region boundaries in periodic nonlinear dynamic systems are deduced.(More)
