【Abstract】 The nonlinear dynamical systems theory to voltage stability analysis is introduced in this paper. The property that the number of equilibrium points varies with operation parameters is investigated, and the stability of every equilibrium point is explored. A simple and efficient method of locating static bifurcation points is presented. Voltage stability regions of the system are constructed in state space considering the dynamics of on load tap changer (OLTC) and load. Finally, the application of the theory to voltage stability analysis is illustrated by time domain simulation.更多还原
