ROTATING SPACE VECTOR CONTROL ALGORITHM OF SUPERCONDUCTING MAGNETIC ENERGY STORAGE (SMES)

The rotating space vector control scheme has the potential ability to track the change of system voltage fastly. This paper proposes the method to the control scheme of superconducting magnetic energy storage (SMES), to achieve fast response to the fluctuation of system voltage. The feasibility of this control scheme under symmetrical and asymmetrical voltage is analyzed, and the comparison of rotating space vector control and conventional vector control is also discussed in this paper. Another reason for the introduction of this method is to decrease calculation cost. Simulation results show that, SMES with the proposed method works better than that with the conventional vector control if system voltage varies.
