【Abstract】 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 rejection 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.更多还原
