Abstract
The design of controller is the important part for static synchronous compensator (D-STATCOM). However, due to the strong decouple and non-linear characteristic of D-STATCOM, the traditional controller cannot meet the demand of the power system. This paper introduces linear auto disturbance rejection controller(LADRC) for D-STATCOM based on its mathematics model and design first-order LADRC for it; and then classical control theory is used to analyze convergence of two-order linear extended state observer (LESO) in frequency domain; at last, the simulation model is made for it, verification shows that ADRC is superior to conventional proportional - integral - derivative controller, it has good tracking performance and immunity characteristics, this paper verify the feasibility of LADRC controller and its controller.
