Abstract: Systems and methods for controlling operation of one or more auxiliary circuits in a wind turbine system are provided. For instance, a grid event associated with the wind turbine system can be detected. In response to the grid event, a control signal can be provided to an auxiliary circuit breaker of the wind turbine system. The auxiliary circuit breaker can be associated with one or more auxiliary circuits that are not directly in a power production path of the wind turbine system. The auxiliary circuit breaker can disconnect the one or more auxiliary circuits from the grid based at least in part on the control signal.

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.

Abstract: In one aspect, a method for controlling the operation of a power generation system configured to supply power to an electrical grid may generally include detecting an occurrence of an islanding event associated with the power generation system and adjusting a regulator gain applied within a regulator of the power generation system to an islanding gain value in response to the detection of the islanding event, wherein the islanding gain value exceeds a maximum gain value defined for the regulator in the event of an occurrence of any ride-through transient event. In addition, the method may include controlling a power converter of the power generation system based on a control signal generated by the regulator as the power generation system is being isolated from the electrical grid and shutting down the power generation system upon isolation of the power generation system from the electrical grid.

Abstract: The present subject matter is directed to a system and method for operating an electrical power circuit connected to a power grid. The electrical power circuit has a power converter electrically coupled to a generator. The method includes monitoring a rotor speed of the generator during operation of the electrical power circuit. The method also includes increasing an operating range of the rotor speed of the generator. Further, the method includes determining at least one of a line-side voltage of a line-side converter of the power converter or a rotor-side voltage of a rotor-side converter of the power converter during operation of the electrical power circuit. Another step include controlling, via a converter controller, a DC link voltage of a DC link of the power converter as a function of one or more of the line-side voltage, the rotor-side voltage, and/or the rotor speed.
