摘　　要：风力发电作为一种清洁能源,在电力系统的应用越来越广泛。文中基于分岔理论,研究不同风速下系统电压的变化过程。结果表明,风力电机在并网过程中,电压会出现Hopf分岔、鞍结分岔、普通静分岔或fold分岔等。这些分岔点的出现,表明系统电压会在运行中发生静态或动态失稳,这也是风力发电机并网的基本特性。As a kind of clean energy, wind power has been widely used in power system. Based on bifurcation theory, it analyzes thebifurcation of power system change process in different wind speed. The results show that Hopf, saddle-node, static and fold bifurcationhave been observed in the process of the wind power integrated into the grid. These bifurcations show that the voltage of system will bestatic or dynamic in operation which is the basic characteristics of wind power integrated into the grid.
