Abstract: A method for reactive power control of a wind farm having a plurality of clusters of wind turbines with a cluster transformer connecting each cluster of wind turbines to a power grid is provided. The method includes receiving, via a plurality of cluster-level controllers, a reactive power command from a farm-level controller. The method also includes generating, via the cluster-level controllers, a cluster-level reactive current command for each cluster of wind turbines based on the reactive power command. Further, the method includes distributing, via the cluster-level controllers, a turbine-level reactive current command to turbine-level controllers of the wind turbines based on the cluster-level reactive current command.

Abstract: An electrical power system includes a cluster of electrical power subsystems, each of the electrical power subsystems including a power converter electrically coupled to a generator having a generator rotor and a generator stator. Each of the electrical power subsystems defines a stator power path and a converter power path for providing power to the power grid. The converter power path includes a partial power transformer. The electrical power system further includes a subsystem breaker configured with each of the electrical power subsystems, and a cluster transformer for connecting each cluster of electrical power subsystems to the power grid. The electrical power system further includes a cluster power path extending between each subsystem breaker and the cluster transformer, and a distortion filter electrically coupled to the cluster transformer. The distortion filter reduces harmonics in current flowing from the electrical power subsystems to the cluster transformer.

Abstract: A method for operating an electrical power system includes detecting a bridge current magnitude in a rotor-side converter or line-side converter of a power converter, the power converter electrically coupled between a generator rotor and a transformer. The method further includes comparing the bridge current magnitude in the one of the rotor-side converter or line-side converter to a primary predetermined threshold. The method further includes disabling bridge switching of one of the rotor-side converter or line-side converter when the bridge current magnitude exceeds the primary predetermined threshold.

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: A method for controlling an electrical power system connected to a power grid includes receiving a reactive power command and a measured reactive power and generating a reactive power error signal based on a difference between the reactive power command and the measured reactive power. Further, the method includes receiving, via a reactive power regulator, the reactive power error signal. Moreover, the method includes generating, via the reactive power regulator, a voltage command based on the error signal. The method also includes generating, via a droop control, a voltage droop signal. In addition, the method includes generating a voltage error signal as a function of the voltage droop signal and at least one of the voltage command or a measured terminal voltage. Thus, the method further includes generating, via a voltage regulator, a reactive current command based on the voltage error signal.
