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 method for operating a multi-level bridge power converter of an electrical power system connected to a power grid includes receiving, via a controller of the power converter, an indication of a transient event occurring in the power grid or the electrical power system. The power converter has a plurality of switching devices arranged in an active neutral point clamped topology. Accordingly, upon receiving the indication, the method includes activating a crowbar algorithm programmed in the controller of the power converter to bifurcate a current received by the power converter into a plurality of different current paths defined by the plurality of switching devices.

Abstract: A system for adjusting environmental operating conditions associated with heat generating components located within a tower of a wind turbine may include a heat generating component located within an interior of the tower, a sensor configured to monitor a heat exchange parameter associated with the wind turbine and a split heat exchange system provided relative to the tower. The split heat exchange system may include a first heat exchanger located within the interior of the tower and a second heat exchanger located exterior to the tower. The system may also include a controller communicatively coupled to the sensor and the split heat exchange system. The controller may be configured to control the operation of the split heat exchange system based at least in part on the monitored heat exchange parameter to adjust an environmental operating condition associated with the heat generating component.

Abstract: A system and method are provided for controlling a wind turbine to protect the wind turbine from anomalous operations. Accordingly, in response to receiving data indicative of an anomalous operational event of the wind turbine, the controller initiates an enhanced braking mode for the wind turbine. The enhanced braking mode is characterized by operating the generator at a torque setpoint that generates maximum available torque for a given set of operating conditions. Additionally, the torque setpoint is in excess of a nominal torque limit for the generator.

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.
