Abstract

This paper presents improvement of transient stability of power systems with superconducting magnetic energy storage (SMES). SMES has been connected at the generator terminal for single machine connected to infinite bus (SMIB). A comparison of performance of proportional type of SMES (P-SMES) proportional-Integral type of SMES (PI-SMES)and that of an Optimally Switched Dynamic Brake (OSDB) suggested by Minisey et al is presented. Transient stability investigations were carried out on SMIB with SMES for diverse loading conditions and different fault clearing times. The results established superior performance of SMES in damping transient swings over optimally switched conventional dynamic brake.
