Abstract: The present disclosure is directed to an automated apparatus and method for testing a crowbar circuit of power converter. The crowbar circuit includes an anti-parallel diode and a voltage-controlled switching element, e.g. a silicon-controlled rectifier (SCR). The method includes implementing a first test sequence for testing operability of the diode and a second test sequence for testing operability of the voltage-controlled switching element. More specifically, the first test sequence determines a first current-voltage feedback that is indicative of the operability of the diode and the second test sequence determines a second current-voltage feedback that is indicative of the operability of the voltage-controlled switching element.

Abstract: The present subject matter is directed to a method for initializing a startup sequence of a wind turbine. The method includes a step of defining a plurality of operating conditions of the wind turbine. As such, upon satisfaction of the plurality of operating conditions, a run-ready signal may be generated, wherein the run-ready signal indicates a readiness of a power converter of the wind turbine to generate power. The method may also include defining a subset of the plurality of operating conditions, wherein the subset of operating conditions are independent of speed conditions of the wind turbine. Another step of the method includes generating a spin-ready signal for the wind turbine upon satisfaction of the subset of operating conditions. The method may also include controlling a rotor of the wind turbine based at least in part on the spin-ready signal.

Abstract: The present subject matter is directed to a system and method for controlling an electrical component, e.g. a power bridge, of a wind turbine using contingency communications. In one embodiment, the method includes receiving, by the electrical component, a standard set of commands for a first time frame. A next step includes receiving, by the electrical component, one or more contingency sets of commands for time frames beyond the first time frame. The method also includes determining if the standard set of commands is received within a start window of the first time frame. A further step includes implementing, by the electrical component, the standard set of commands during the first time frame if the standard set of commands is received within the start window. The method also includes implementing, by the electrical component, one of the contingency sets of commands received during a previous time frame if the standard set of commands is not received within the start window.

Abstract: A connection for parallel bridge circuits in a power converter is provided. In particular, a power converter can be used to provide a desired power to a load, such as a generator, motor, electrical grid, or other suitable load. The power converter can include a plurality of bridge circuits coupled in parallel. A bridge output of each of the parallel bridge circuits can be coupled together at the load instead of at the power converter. In particular, the parallel bridge circuits can be coupled together at a location that is physically proximate the physical location of the load, such as at a plurality of terminals associated with the load. By doing so, stray inductance associated with conductors used to couple the bridge outputs of the parallel bridge circuits to the load can be effectively coupled between the parallel bridge circuits.

Abstract: A control system includes first and second fundamental control units for generating first and second fundamental commands, and a compensation control unit. The compensation control unit includes first and second calculation elements and a comparator for comparing first and second modulation indexes. When the first modulation index is less than the second modulation index, the first calculation element generates a first source-side compensation command. When the first source-side compensation command is not sufficient to balance the neutral point voltage, the first calculation element further generates a first line-side compensating command. When the first modulation index is greater than the second modulation index, the second calculation element generates a second line-side compensation command. When the second line-side compensation command is not sufficient to balance the neutral point voltage, the second calculation element further generates a second source-side compensating command.
