Series Voltage Sag Compensation Using Series Type SMES with Open-Circuit Protection

Abstract

In this paper, the voltage sag compensation using series type SMES (Superconducting Magnetic Energy Storage) with open-circuit protection is proposed. The voltage sags and momentary interruptions during the fault occurred can be mitigated. For open-circuit protection, the faulted incoming line is disconnected and the new current path is made. The control scheme is proposed for voltage sag compensation and open-circuit protection. Simulations of voltage sag compensation and open-circuit protection demonstrated the validation of the proposed circuit and control sequence of switches.
