摘要:

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.

关键词: 风电系统, Hopf分岔, 静止无功补偿器, 线性反馈, 电压稳定

Abstract:

For Hopf bifurcation at equilibrium point in wind power system, Hopf bifurcation 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 var 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.

Key words: wind power system, Hopf bifurcation, static var compensation, linear feedback, voltage stability
