摘　　要：为了保证新型电力系统下机组及系统的稳定性,提出一种针对汽轮机调速系统的互联与阻尼分配无源控制器设计方法。首先,以哈密顿系统理论为基础,对系统能量的动态过程进行描述,分析了哈密顿系统结构对系统能量的影响。然后,采用变量梯度法构建包含调速系统的系统能量函数,以注入能量的导数最小为约束条件确定了系统的阻尼矩阵,克服了互联与阻尼分配无源控制器设计过程中确定系统阻尼矩阵困难的问题,完成了汽轮发电机调速系统互联与阻尼分配无源控制器的设计。最后,在MATLAB/Simulink中搭建单机无穷大系统的模型,验证了本文设计控制器的有效性。To ensure the stability of units and systems under the new power system,a design method of interconnection and damping assignment passivity-based controller for steam turbine speed control system is proposed.Firstly,based on the theory of Hamiltonian system,the dynamic process of power system is described from the perspective of energy,and the influence of the structure of Hamiltonian system on the system energy is analyzed.Then,the variable gradient method is used to construct the system energy func⁃tion including the speed control system.The damping matrix of the system is determined with the constraint of minimizing the deriva⁃tive of injected energy.The difficulty of determining the system damping matrix in the design process of the interconnection and damping assignment passivity-based controller is overcome,and the design of the interconnection and damping assignment passivitybased controller is completed.Finally,the proposed method is used to build a model of single-machine infinity bus system in MATLAB/Simulink,and the effectiveness of the controller designed in this paper is verified.
