针对风电系统平衡点的Hopf分岔，计算了含静止无功补偿器风电系统的Hopf分岔点，并通过解析算法判断Hopf分岔类型，分析了无功功率及静止无功补偿器对风电系统电压稳定性的影响．为了消除Hopf分岔，提出采用线性反馈控制方法控制风电系统的Hopf分岔．实验结果表明，风电系统无功功率增加导致系统出现Hopf分岔，静止无功补偿器通过补偿无功功率延迟Hopf分岔，提高系统的电压稳定域，线性反馈控制方法有效地消除了风电系统的Hopf分岔．

英文摘要：

For Hopf bifurcation at equilibrium point in wind power system, Hop/ bllurcatlon point was calculated based on the continuation method the type of Hopf bifurcation was determined by the parsing algorithm in the wind power system with static vat compensator the effect of reactive power and static var compensator on voltage stability were analyzed in the wind power system. In order to eliminate Hopf bifurcation, the linear feedback control method to control Hopf bifurcation was presented. The results show that the increase of reactive power in wind power system causes Hopf bifurcation static var compensator can compensate reactive power to delay Hopf bifurcation and improve the system voltage stability region and the linear feedback control method effectively eliminates Hopf bifurcation of the wind power system.
