Improvement of transient stability of the power system using small Magnetic Energy Storage

Power system is a huge labyrinth of generation, transmission and large scale distribution of electrical power. Disturbances in the power system cause ineffective transfer of power and create problems to system stability. With the advancement of superconducting technology, Superconducting Magnetic Energy Storage device (SMES) can be used in stabilizing the system. In this paper the effects of SMES on Single Machine connected to Infinite Bus bar system, is studied. The SMES unit dampens the power system oscillations and improves the dynamic performance.
