Beschreibung
Zusammenfassung:	The present subject matter is directed to an electrical power circuit connected to a power grid 242 and method of operating same. The electrical power circuit has a power converter 210 electrically coupled to a generator 118, such as a doubly-fed induction generator, having a rotor 122 and a stator 120. Thus, the method includes operating rotor connections 124 of the rotor 122 of the generator 118 in a wye configuration during a first rotor speed operating range. Further, the method includes monitoring a rotor speed of the rotor 122 of the generator 118. Thus, the method also includes transitioning the rotor connections 118 of the rotor 122 from the wye configuration to a delta configuration if the rotor speed changes to a second rotor speed operating range.
