Small-Signal Stability Analysis in SMIB Power System

Abstract

This chapter investigated the small-signal stability problem in a single-machine infinite bus (SMIB) system. Analyses are carried out based on Heffron–Philips model of a SMIB power system. The differential equations of the flux-decay model of the synchronous machine are linearized and a state-space model is constructed. From the resulting linearized model, certain constants known as the K constants (K1–K6) are derived, which are the functions of machine and system impedances as well as operating point. The state-space model is then used to examine the eigenvalues and to ensure adequate damping of the dominant modes. The method of small-signal stability analysis based on frequency ...
