AID IMPLEMENTATION OF THE LEVEL OF A TRANSITIONAL LEVEL WITH UNLESS PHASE PREPARATION AND PHASE PREPARATION OF THE TRANSITIONAL WINDOW

摘要

A bias voltage vectorially added to the controllable voltage injected in series with the line voltage of a transmission line reduces the required MVA rating for a unified power flow controller (UPFC) in applications where the power in the transmission line only flows in a single direction, or where the range of the transmission angle is otherwise unequal about zero.
