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: A control system includes a fundamental control unit, first and second compensation control units, a switch control unit, and a switch implementation unit. The fundamental control unit generates fundamental commands to implement fundamental power conversion operation for a converter. The first compensation control unit generates a first compensation signal for injection into the fundamental command to balance neutral point voltage when the converter is in operation in a first state. The second compensation control unit generates a second compensation signal for injection into the fundamental command to balance neutral point voltage when the converter is in operation in a second state. The switch control unit detects first and second states of the converter and provides first and second switch signals respectively. The switch implementation unit switches the fundamental control unit to communicate with the first and second compensation control units according to the first and second switch signals respectively.

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.

Abstract: Systems and methods for reducing current imbalance between parallel bridge circuits used in a power converter of a power generation system, such as a wind driven doubly fed induction generator (DFIG) system, are provided. The power converter can include a plurality of bridge circuits coupled in parallel to increase the output power capability of the system. Each of the bridge circuits can include a pair of switching elements, such as insulated gate bipolar transistors (IGBTs), coupled in series with one another. The switching elements of the parallel bridge circuits can be controlled, for instance, using control commands (e.g. pulse width modulation commands) according to a substantially non-interleaved switching pattern. The timing of the control commands according to the substantially non-interleaved switching pattern can be adjusted to reduce current imbalance between the parallel bridge circuits.
