Study on Small Signal Stability Based on a Synchronous Generator Model with Field Mutual-leakage Reactance

Abstract

Power system small signal stability studies have been carried out using a synchronous machine model with field mutual-leakage reactance called Canay reactance in the d-axis equivalent circuit. The influence of Canay reactance on effects of power system stabilizer (PSS) was checked with eigenvalue calculation method. The values of Canay reactance reported in the literatures were also investigated statistically, and an approximated expression possible to be adopted in stability studies was also proposed.
