“…The current overload values are given in Table I. Agee [18] points out that while the stator current requirements are given, it is unlikely that generation owners will operate beyond this curve as most machines are not built with excess armature thermal capability. This situation, of course, does not apply to the Powerformer, which can maintain currents in excess of this standard curve.…”

Abstract-This paper provides an overview of a dynamic analysis carried out on a modified Nordic test system to determine the impact of the Powerformer on voltage stability. The unique aspects of the Powerformer will be highlighted and the modeling of long-term dynamic elements, especially those pertinent to the study of the Powerformer will be discussed. Overexcitation limiter models created for use in the PTI PSS/E analysis program will be discussed and utilized. The importance of choosing the right value of overexcitation limiter gain will be highlighted and discussed. The impact of the location of the Powerformer and the compensation scheme utilized on the time to collapse following a system contingency will also be highlighted and discussed.Index Terms-Long term dynamics, power system modeling, power system planning, power system security, voltage collapse, voltage stability.
