In this thesis, the basic structure and the operation principle of magnetic valvecontrollable reactor are studied, and the mathematic model is also established. On thebasis of these, the working characteristics are analyzed completely. An effective methodof restraining the harmonics of the controllable reactor poured into power grid itself byusing phase-shifting winding is presented for the first time, and corresponding work suchas the theoretical analysis and mathematic derivation have been done in the following.Furthermore, the high speed excitation of magnetic valve controllable reactor is alsodiscussed;the theoretical analysis indicates that the controllable reactor can get a veryfast respond velocity with a certain type of control strategy. H∞ control strategy and thespecial high speed excitation circuit are adopted to achieve the suppression of thevoltage fluctuation and flicker based on controllable reactor. The EMTDC/PSCAD basedsimulation results verify the effectiveness and correctness of the proposed scheme.
