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 are highlighted and the modeling of long-term dynamic elements, especially those pertinent to the study of the Powerformer are discussed. Overexcitation limiter models created for use in the PTI PSS/E analysis program are discussed and utilized. The importance of choosing the right value of overexcitation limiter gain is 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 is also highlighted and discussed.
