Abstract
In this paper, a combined controller of a superconducting magnetic energy storage (SMES) with series phase compensator for the stabilization of a power system is proposed. By the use of a series compensator, the SMES becomes capable of absorbing the generator accelerating power during a short circuit fault. In addition, the fault current is limited by the energy absorption as well as by the leakage reactance of a series transformer. A new control scheme for damping control of the generator swing has been proposed that is suitable for a SMES with series configuration. Some numerical results demonstrate significant effectiveness for the enhancement of power system stability and fault current limiting.
