A simplified physical model of magnetic controlled transformer based on the split-core magnetic controlled reactor is proposed.And then,three possible states of the magnetic transformer are analyzed,and the amplitude of reactive power compensation and harmonic content with the change of the control current are obtained through detailed mathematical derivation and analysis on the basis of the different operating states of magnetic controlled transformer.Referring to the transformer design principles,the simulation analysis of 1600 k VA/35 k V magnetic controlled transformer is conducted,obtaining the results of reactive power compensation and harmonic content along with the change of control current,providing some guidance for the further study of the magnetic controlled transformer.
