摘要
本文给出了应用次最优控制理论,设计励磁和调速的多参量反馈附加控制器来抑制大型汽轮发电机组轴系扭振,并同时改善电力系统的动态品质的结果。数字仿真表明:所设计的多参量反馈附加控制器,不仅有效地抑制了机组轴系的扭振,而且大幅度提高了发电机的稳定运行水平。
Using the sub-optiaml control theory, this paper presents a new method of excitation and governor supplementary controller for suppressing torsional oscillation of large turbine—generator shafts. Simulation results show that the designed controller can suppress effectively torsional oscillation of shafts as well as improve the stability of power system.
