System stability and protection from any disturbances are significant issues in a recent power system especially in a deregulated power system. In this paper a Superconducting Fault Current Limiter (SFCL) assembled with a series damping resistor is investigated as a powerful controller for the transient stability enhancement of power systems. The application of series damping resistor controlled by SFCL combined with a Superconducting Magnetic Energy Storage (SMES) for power system stabilization is proposed and the effectiveness is investigated in detail. The SFCL with a series damping resistor is capable of absorbing the accelerating power of generator effectively, by which the capacity of SMES is significantly reduced. As a result, the power system dynamic stability as well as the transient stability has been effectively enhanced by the SMES with SFCL.
