A voltage sag compensating system using a SMES is presented. Based on the previous works, we have carried out experiments for voltage sag compensation on the laboratory-built system to validate the proposed minimum energy injection voltage sag compensation algorithm. In order to improve the compensating performance of the system, two-degree of freedom voltage control is proposed. In this paper, the circuit configuration and the feedback voltage control system of compensator are described and the experimental results are reported.
