Abstract: Two stage matrix converter (TSMC) because of its excellent electrical performance, in unified power flow controller (UPFC) has great application value. This paper analyzes the space vector modulation strategy of two TSMC and predictive model was established on TSMC-UPFC series side, on the basis of the series side predictive current control strategy based on TSMC-UPFC is proposed. Simulation results show that the control strategy proposed in this paper has good adjustment effect on line flow, can quickly and accurately track the reference value, small overshoot, and has better dynamic and static performance.
