Abstract: A method for operating a multi-level bridge power converter of an electrical power system includes connecting a plurality of phases of the power converter to a common terminal at a DC side of the power converter so as to effectively equate the plurality of phases at a common electrical potential. The method may also include monitoring, via a controller, a plurality of devices of the power converter for faults. Upon detection of a fault in one or more of the plurality of devices, the method includes activating, via the controller, one or more protection devices of a crowbar of the power converter to prevent additional faults from occurring in remaining devices of the plurality of devices by diverting energy away from the remaining devices of the plurality of devices.

Abstract: The present disclosure is directed to a system and method for reducing ice or condensation that forms on a power component of a wind turbine during a power outage. The method includes determining an ambient temperature near the power component; providing one or more parameters of the power component; determining a down time of the power component for the power outage; determining a wait time for the power component to stay offline as a function of the ambient temperature, the one or more parameters, and the down time of the power component; and, heating the power component for the wait time before supplying power to the power component such that a surface temperature of the power component is raised above the ambient temperature. As such, the method prevents the power component from being energized when condensation or ice may be present.

Abstract: A system and method for pre-charging a DC link of a multi-level power converter, to reduce electrical transients or to decrease a charging current when a converter contactor/disconnect switch is closed, is described. The systems and methods of the present disclosure also provides a new and simplified system for pre-charging a DC link of a multi-level power converter by leveraging a neutral point of a multi-level power converter and a single-line connection to the grid side of the power converter. The DC link charger of the present disclosure, therefore, is capable of reducing the quantity of dedicated superfluous hardware and/or excess resistors, contactors, transformers, fuses, diodes, balancing components, rectifier modules, etc. demanded by conventional systems. Reduced quantities of electronic components and hardware can thereby decrease system costs per unit and lead to significant cost savings.

Abstract: A system and method are provided for controlling a wind turbine. Accordingly, a controller of the wind turbine detects a loss of traction of the slip coupling between a generator and a rotor of the drivetrain of the wind turbine. In response to detecting the loss of traction, the controller overrides a generator torque setpoint to alter a rotational speed of the generator. In response to the altered rotational speed of the generator, the traction of the slip coupling is increased. Increasing the traction of the slip coupling facilitates an application of generator torque to the drivetrain of the wind turbine.
