| 摘 要： | 以交直流并联系统为研究对象,综合考虑发电机和高压直流(HVDC)输电系统的动态调节过程,建立系统的非线性动态模型。并运用直接反馈线性化理论和H2控制理论,设计HVDC与发电机励磁的协调非线性控制器,其中H2控制律采用线性矩阵不等式(LMI)方法得出。仿真结果表明,所设计的控制器鲁棒性好,可以有效地提高交直流系统的暂态稳定性。

| Abstract: | The nonlinear dynamic model was set up for a parallel AC/DC system, in which the dynamic regulating process of the generator and HVDC was considered comprehensively. The nonlinear controller of HVDC collaborated with the excitation of generator was designed according to the direct feedback linearization theory and H2 control theory. By making use of the linear matrix inequality(LMI) approach, H2 control law was obtained. The simulation results show that the controller has strong robustness and can effectively enhance the transient stability of the system. |
