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 ,该控制规律可以提高电力系统的暂态稳定性和动态性能
A method of presetting power angle feedback is proposed. The generalized controlled Hamiltonian system model of multi-machine steam turbine governing system is deduced. Then the design of passive controller based on Hamiltonian structure is proposed. All variables of the control strategy are locally measurable, only related to the state quantities of this unit, and have nothing to do with the state quantities of other units and the parameters of the transmission network. The simulation results of 4-machine system show that this control law can improve the transient stability and dynamic performance of the power system
