Abstract
In almost all the literatures, the qualitative assessment
of transient angle stability extracts the angle
information of generators based on the swing curve.
As the angle (or angle difference) of concern and the
threshold value rely strongly on the engineering
experience, the validity and robust of these criterions
are weak. Based on the stability mechanism from the
extended equal area criterion (EEAC) theory and
combining with abundant simulations of real system,
this paper analyzes the criterions in most literatures
and finds that the results could be too conservative or
too optimistic. It is concluded that misjudgment
would be taken if an angle (or angle difference) of
concern departing from the concept of the controlling
mode or a constant threshold value is used in the
criterion.
