摘要
提出了一种预置功角反馈的方法 ,推导出多机系统汽轮机调速系统的广义受控哈密顿系统模型 ,进而在哈密顿结构的基础上进行无源化控制器的设计。控制策略的所有变量都是本地可量测的 ,只与本机组的状态量有关 ,与其他机组的状态量和输电网络的参数无关 ,因而具有分散性。 4机系统仿真结果表明 。
This paper proposes a m ethod of the angle pre- feedback to form ulate the generalized forced Ham iltonian system model for a m ulti- machine speed governor control system .Furthermore,a passive controller is designed based on the schem e of the Hamiltonian structure.All the variables in the control law are only relevantto the state variables of the local generator and are independent of the state variables of other units and the param eters of the transm ission network,therefore it is a decentralized control strategy.Simulation results of a4- machine system show that the controller can enhance the transient stability and the dynam ic perform ance of the power system.
