Abstract

Maximum transmitted power Nodes critical power Tap-changing Voltage stability
It was long known that tap-changing transformers can affect voltage stability of power systems. Evaluation of these effects are provided in this paper. Influence of tap-changing transformer on maximum transmitted power and nodes critical voltages, from the point of view of voltage stability, are clarified. Wide range of tap-changing are used in this clarification and stability margins excursions are explored.
