中文摘要	设计了应用于交直流互联电力系统的直流功率调制的非线性鲁棒自适应控制器。该控制器基于驱动各互联区域电网的惯量中心至统一平衡点的设计思想,采用广域测量系统的全局信号,用以阻尼交直流互联系统的区域间功率振荡。采用反步法设计的自适应鲁棒控制规律使控制器对未知参数具有自适应性,对模型误差、扰动和平衡点变化具有较强的鲁棒性。仿真结果表明,与传统的线性直流功率调制控制器相比,该控制器对联络线的功率振荡具有优良的阻尼性能,可显著提高输电极限,而且能很好地适应运行点的变化。; The robust adaptive control law is proposed for a HVDC power modulation controller of the interconnected AC/DC power system. Based on the design idea of driving the center of inertia (COI) of different areas to a stable equilibrium point, the proposed controller is applied to damp inter-area oscillation of interconnected AC/ DC system using global signals of a wide area measuring system (WAMS). Designed by the back-stepping method, the robust adaptive control law is adaptive to the unknown parameters and is robust to model error, disturbances and different equilibrium points. Computer results show that the controller proposed is obviously superior to the conventional DC power modulation controller in damping inter-area oscillation and enhancing the power transfer limit. In addition, its performance can well adapt to the change of the equilibrium point.; 国家自然科学基金重点项目(50337010) 香港政府大学研究基金资助项目(CityU 1/00C)。
