摘　　要：考虑电力系统的非线性特性,基于H am ilton能量函数理论,设计了一种新的非线性稳定控制器。阐述了广义哈密顿系统理论及H am ilton能量函数理论,然后针对包含静止无功补偿器的单机无穷大系统建立非线性数学模型,并应用哈密顿系统理论对其进行实现,再从能量的观点出发,利用能量函数法设计系统稳定控制器。单机无穷大系统数字仿真结果验证了该控制律的有效性。A new nonlinear controller for power system with SVC is designed based on Hamiltonian energy function, and the nonlinear property of the dynamic system is well preserved and utilized. Generalized Hamiltonian system theory and Hamiltonian energy function are introduced in detail, then a nonlinear mathematic model as well as its Hamiltonian realiztion is presented for single-machine infinite-bus system with SVC. Simulation results verify the effectiveness of the controller.
