Abstract :
Dynamic voltage stability analysis is mainly based on the time-domain solution of power system differential equations. The modeling of each power element has a great influence on the correctness and complexity of stability analyzing. It is a significant work to model appropriately for simplifying calculation and drawing out principal contradiction. Firstly, the dynamical mechanism of voltage stability is summarized. More, this paper employs the perturbation method and integral manifold theory as a tool for studying on the relationship of stability between the reduced-order system and original system. An important conclusion is reached that the power system quasi-steady-state model can be used for dynamic voltage stability analysis. At the same time, it must be caution to neglect the dynamic of the load in voltage stability analysis.
