Transient stability studies in SMIB system with detailed machine models

This paper presents a detailed transient stability analysis using various machine models. It highlights on the accuracy of the approximated models of synchronous machines for power system transient stability analysis. The transient stability simulation is performed on a SMIB system considering four different detailed models of generators and the classical model. The exciter dynamics is represented by IEEE Type 1 Exciter model in the detailed analysis. Exclusive comparison of performance using various models is done. Transient Stability Analysis and Critical Clearing Time (CCT) is evaluated for specified fault at various locations. © 2011 IEEE.
