Abstract: A method for operating a multi-level bridge power converter of an electrical power system connected to a power grid includes receiving a commanded state for one or more switching devices thereof. The method also includes receiving a gate-emitter voltage of one or more of the switching devices. Further, the method includes comparing, via at least one comparator, the gate-emitter voltage of the one or more switching devices to a reference voltage range corresponding to the commanded state of the one or more switching devices. In addition, the method includes determining an actual state of the one or more switching devices based on the comparison. Thus, the method also includes implementing a control action based on the actual state of the one or more switching devices.

Abstract: A method for operating a multi-level bridge power converter of an electrical power system connected to a power grid includes providing a plurality of switching devices of the power converter in an active neutral point clamped topology. The method also includes operating the plurality of switching devices in a plurality of operating states such that current simultaneously flows through at least two parallel recovery paths of the plurality of switching devices during operation of the power converter to minimize a commutation path of the current when at least one diode of the plurality of switching devices recovers, thereby reducing parasitic inductance affecting the recovering antiparallel diode or the switch.

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.

Abstract: A power electronics assembly for a power generation system includes a housing and an attenuator card positioned within the housing. The attenuator card may include at least one printed circuit board for a high-voltage attenuator circuit. The power electronics assembly also includes a potting material at least partially filling the housing on one or more sides of the attenuator card, a detachable end cap positioned at a first end of the housing, and multi-phase wiring communicatively coupled to the high-voltage attenuator circuit through the end cap.

Abstract: An electrical power system connected to a power grid can include a generator having a stator and a rotor and a power converter. The stator is connected to the power grid via a stator power path. The power converter can include a line-side converter coupled to the power grid via a converter power path and a rotor-side converter coupled to a rotor bus of the rotor and the line-side converter via a DC link. The rotor-side converter is configured to convert a DC power on the DC link to an AC signal for the rotor bus. The power system can also include an active filter having one or more active controlled components. The active filter is coupled in parallel with the rotor-side converter to reduce harmonics of the electrical power system.

Abstract: A method for optimizing reactive power generation of an electrical power system includes generating, via a plurality of cluster-level controllers, a cluster-level reactive power command for each cluster of electrical power subsystems based on a system-level reactive power command. The method also includes determining, via the cluster-level controllers, a subsystem-level reactive power command for each of the electrical power subsystems based on the cluster-level reactive power command. Further, the method includes evaluating, via a plurality of subsystem-level controllers, reactive power capability of a plurality of reactive power sources within each of the electrical power subsystems. Moreover, the method includes generating, via each of the subsystem-level controllers, an actual reactive power for each of the electrical power subsystems based on the evaluation by allocating a portion of the subsystem-level reactive power command to each of the plurality of reactive power sources.
