研究包含静止无功补偿器的电力系统非线性控制的一种新方法。文中首先给出包含静止无功补偿器的电力系统非线性数学模型,再利用广义哈密顿(Hamilton)系统理论,对其进行哈密顿实现,并提出了一种L2增益意义下的干扰抑制方法,得到了实现干扰抑制的控制规律。详细阐述了该方法的理论依据和控制律的具体设计过程。单机无穷大系统情况下的仿真结果表明,该方法所设计的控制规律能有效抑制干扰的影响,提高电力系统暂态稳定性。
A new method of nonlinear control of power system including static var compensator is studied. In this paper, the nonlinear mathematical model of power system with static var compensator is given first, and then the Hamiltonian system theory is used to realize the Hamiltonian system. And an interference suppression method based on L2 gain is proposed. Get the control law to realize the interference suppression. The theoretical basis of the method and the specific design process of the control law are elaborated. The simulation results under single-machine infinite system show that the control law designed by this method can effectively restrain the influence of interference and improve the transient stability of power system.
