运用延拓法追踪以双馈感应风电机(DFIG)为代表的风电系统的平衡解流形，并基于分岔理论，分析平衡解流形的分岔点。提出了一种基于高通滤波器(washout filter)技术的SVC模型，对风电系统发生的霍普夫(Hopf)分岔进行分岔控制，改变与系统分岔相关的雅可比矩阵特征值，不但消除了Hopf分岔点，还提高了电压幅值，扩大了电压稳定裕度。仿真结果和时域仿真验证了提出的方法是正确可行的。

The continuation method was used to track the balance flow of wind power system connected by a doubly fed induction generator (DFIG), also this paper analyzed the bifurcation points based on the bifurcation theory. A novel static var compensator (SVC) model based on washout filter technology was proposed to control Hopf bifurcation happened in wind power system and to alter the Jacobian matrix’s eigenvalue related to the system bifurcation, which not only eliminates the Hopf bifurcation points, but also en-hances the voltage amplitude and extends the voltage stability margin. The simulation results and time domain simulation verify that the new approach is feasible.
