| 中文摘要 |
| 采用Hamilton函数方法研究了包含静止无功补偿器(SVC)和非线性负荷的电力系统的反馈控制问题. 首先建立了系统的非线性微分代数方程模型, 通过预置状态反馈完成了耗散Hamilton实现. 然后利用该耗散实现结构,通过阻尼注入方式设计了基于能量的SVC非线性控制器. 本文所设计的控制器结构简单, 物理意义明确. 仿真结果表明该控制器能有效提高电力系统的暂态稳定性. |
| 英文摘要 |
| Using the Hamiltonian function method, this paper investigates the feedback control of power systems with static var compensator(SVC) and nonlinear loads. First, based on the nonlinear differential algebraic model of power system, a dissipative Hamiltonian realization is proposed via pre-feedback control. Then, by making use of the Hamiltonian realization structure, an energy-based SVC controller is constructed by the means of damping injection. The proposed
controller has the advantage of simple structure and clear physical meaning. Simulation result shows that the control scheme can effectively improve the transient stability of the power system. |
