摘　　要：针对配电网静止同步补偿器(distribution static synchronous compensator,D-STATCOM)系统非线性、多变量、强耦合特性、D-STATCOM系统模型的不确定性和不确定性干扰对D-STATCOM控制的影响,研究了D-STATCOM的自抗扰控制技术,提出了一种新型的D-STATCOM自抗扰控制策略,当D-STATCOM系统参数发生变化或遇到不确定扰动时,D-STATCOM控制器仍能保持良好的控制性能以及强的自适应性和鲁棒性。给出了控制器设计的详细过程,并在MATLAB/Simulink环境中建立了系统的仿真模型,给出了仿真和实验结果。仿真和实验结果证明了自抗扰控制策略的正确性和有效性。In allusion to the affects of nonlinearity, multi-variables and strong coupling features of distribution static synchronous compensator （D-STATCOM） as well as the uncertainty of D-STATCOM model and uncertain interferences on D-STATCOM control, the active disturbance rejection control for D-STATCOM is researched, and a novel active disturbance re）ection control strategy for D-STATCOM is proposed. Thus, when parameters of D-STATCOM system vary or uncertain interferences occur, the D-STATCOM controller can maintain good control performance and strong adaptability and robustness. A MATLAB/Simulink based simulation model of the proposed control system is built and results from simulation and experiments, which prove the correctness and effectiveness of the proposed control system, are given. The detailed design process of the controller is also given.
