Several voltage collapses have had a period of slowly decreasing voltage followed by an accelerating collapse in voltage. This paper analyzes this type of voltage collapse based on a center manifold voltage collapse model. The essence of this model is that the system dynamics after bifurcation are captured by the center manifold trajectory and it is a computable model that allows prediction of voltage collapse. Both physical explanations and computational considerations of this model are presented. The authors clarify the use of static and dynamic models to explain voltage collapse. Voltage collapse dynamics are demonstrated on a simple power system model.
