Abstract: A power system includes a converter configured to be electrically coupled to a power source, the power source including an energy storage device. An inverter coupled to the converter can transfer power between the converter and an electrical distribution network. A control system coupled to the converter and to the inverter can gradually adjust a voltage across at least one of the converter or the inverter during at least one of a shutdown sequence or a startup sequence of the power converter system.

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 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 controlling a power converter of a wind turbine power system connected to an electrical grid. The wind turbine power system has a generator and the power converter has rotor-side converter and a line-side converter. The method includes monitoring an electrical parameter of at least one of the wind turbine power system or the electrical grid. In response to detecting a transient event in the electrical grid, the method includes temporarily disabling the line-side converter of the power converter from the electrical grid. Either during the transient event or after the transient event is over, the method includes implementing a control action for the line-side converter of the power converter. Further, the method includes enabling the line-side converter of the power converter to the electrical grid.

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 grounding circuit for a backup power source used to power a pitch motor of a pitch system in a wind turbine is provided. The grounding circuit includes one or more switching elements configured to selectively couple the backup power source to a charging circuit based on a state of a first interface element. The grounding circuit further includes one or more switching elements configured to selectively couple the backup power source to ground based on a state of a second interface element. The grounding circuit includes at least one circuit protection device coupled between the backup power source and the charging circuit. When the backup power source is coupled to the charging circuit and subsequently coupled to ground, the at least one circuit protection device is configured to decouple the backup power source from the charging circuit.

Abstract: Systems and methods for allocating reactive power production in a doubly-fed induction generator (DFIG) wind turbine system including a DFIG and a power converter including a line side converter and a rotor side converter are provided. A method can include obtaining a reactive power production requirement, obtaining one or more operating parameters for the DFIG and the line side converter, and determining a priority ratio based at least in part on the one or more operating parameters. The priority ratio can be a ratio of reactive power production between the DFIG and the line side converter. The method can further include controlling the DFIG and the line side converter based at least in part on the reactive power production requirement and the priority ratio such that the combined reactive power production from the DFIG and the line side converter meet the reactive power production requirement.

Abstract: Systems and methods for operating a power system having a doubly fed induction generator are provided. In example implementations, a power system can include a power converter. The power converter can include a line-side converter, a DC link, and a rotor-side converter. The rotor-side converter is configured to convert a DC power on the DC link to an AC signal for a rotor bus. The system can include a control system having one or more control devices. The one or more control devices are configured to operate the rotor-side converter in an overmodulation regime to provide the AC signal for the rotor bus
