Abstract: The present subject matter is directed to a system and method for operating an electrical power circuit connected to a power grid. The power circuit includes a power converter electrically coupled to a generator. The method includes monitoring at least one speed condition of the generator during operation of the power circuit. Another step includes determining one or more voltage conditions of the power circuit. The method also includes calculating a maximum reactive current for the generator as a function of at least one of the speed condition or the one or more voltage conditions. Thus, the method also includes operating the generator based on the maximum reactive current so as to prevent an actual modulation index of the power converter from exceeding a predetermined threshold.

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

Abstract: The present subject matter is directed to a method for managing and/or categorizing trip faults of an electrical component, such as power converter, of a wind turbine. The method includes receiving, via a local controller of the wind turbine, an indication of at least one trip fault in the electrical component of the wind turbine. The method also includes determining, via the local controller, a unique identifier for the trip fault. More specifically, the unique identifier contains information regarding a type of the trip fault and at least one of an origin or a cause, of the trip fault. Further, the method includes sending, via the local controller, the unique identifier to a supervisory controller of the wind turbine. Thus, the method also includes implementing, via the supervisory controller, a control action based on the unique identifier.
