<strong>SMIB</strong> Eigenvalues<br />
• Extremely large negative eigenvalues are often<br />
caused by particular exciter models such as<br />
EXST1_GE and REXS which contain extremely<br />
fast feedback loops<br />
• These models require special consideration in<br />
the numerical integration algorithm and are<br />
dealt with by using sub-interval integration<br />
