The scalar models of transmission line and TSMC’s inverting side were established in dq frame, the dual-input dual-output scalar models were simplified into the single-input single-output compound vector models by introducing compound vector, an three-loop control strategy which had the function of decoupling was proposed accordingly by adopting the models. It is showed by the MATLAB/SIMLINK simulation that the system not only realizes a decoupling control of power flow but also has good dynamic and steady performances.
