摘　　要：多馈入HVDC越来越成为系统规划和系统运行分析研究的重点课题。研究表明,附加控制器可以显著提高多馈入HVDC的稳定性。针对多馈入HVDC,将微分几何状态反馈精确线性化方法与时域H∞控制理论相结合,在建立典型多馈入HVDC模型的基础上,详细分析推导并设计了多馈入HVDC鲁棒非线性附加稳定控制器的控制决策,得出稳定控制规律。对于该控制器的特性和作用进行了讨论,为其实际应用提供了理论基础。Muhi-infeed HVDC have been the focus of Electric Power System programming and operation researching. Recently the studying has shown that the complementary controllers for HVDC can be used to improve the power system stability. In this paper, using the combination of feedback linearization approach and linear H∞ controlling theory, basing on the model of a multi-infeed HVDC, a nonlinear robust control law for muhi-infeed HVDC is designed in detailed and discussed the characteristic and the effect. It also provides a theoretical basis for practical application.
