4.6 Effect of excitation system

In this section, the effect of excitation system on the small-signal stability performance of the SMIB system is examined in frequency domain [3]. For simplicity, let us assume that the exciter is simply a high constant gain KA, i.e., TA = 0.

Now from Equation (4.70), TAΔEfd = − ΔEfd − KAK5Δδ − KAK6ΔEqsi148_e + KAΔVref with TA = 0 and ΔVref = 0 gives

ΔEfd=KAK5ΔδKAK6ΔEq
