Abstract: The present disclosure is directed to a system and method for optimizing operation of a wind turbine. The method includes providing a voltage regulator between a power grid and the wind turbine. The voltage regulator is configured to control at least one voltage condition of the wind turbine. Another step includes monitoring, via one or more sensors, at least one operating condition and at least one voltage condition of the wind turbine. The method also includes comparing, via a controller, at least one of the operating condition or the voltage condition with a predetermined threshold to determine a margin-to-threshold ratio. Thus, a further step includes controlling the voltage regulator based on the comparison so as to maximize the margin-to-threshold ratio.

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: A method for operating a power generation system that supplies power for application to a load is disclosed. The method may generally include receiving, at a power converter, an alternating current power generated by a generator operating at a speed that is substantially equal to its synchronous speed and converting, with the power converter, the alternating current power to an output power, wherein the power converter includes at least one switching element. In addition, the method may include receiving a control command to control a switching frequency of the at least one switching element and adjusting the switching frequency to an adjusted switching frequency that is substantially equal to a fundamental frequency of the load.

Abstract: The present subject matter is directed to a system and method for operating a wind turbine connected to a power grid. The method includes receiving, via a controller, one or more current feedback signals from one or more electric current sensors of the wind turbine. Another step includes determining, via the controller, if a ground fault is occurring in the wind turbine based on the current feedback signals. In response to detecting a ground fault, the method includes tripping one or more electrical components of the wind turbine and electrically de-coupling the wind turbine from the power grid.

Abstract: A method for controlling a transformer includes specifying, in one or more control devices, an initial operating limit (e.g. an initial current limit or an initial temperature limit) for one or more windings of the transformer. Further, the method includes monitoring, via one or more sensors, at least one electrical condition of the one or more windings of the transformer (e.g. current or voltage). The method also includes receiving, by the one or more control devices, a signal indicative of the at least one electrical condition of the one or more windings of the transformer. As such, the method further includes adjusting, by the one or more control devices, the initial operating limit based at least in part on the at least one electrical condition of the one or more windings of the transformer.

Abstract: A method for compensating for flicker induced by a generator connected to a power grid includes determining, via a controller of the wind turbine, a nominal reactive current command for a rotor of the generator. The method also includes measuring, via at least sensor, one or more operational parameters of at least one of the generator or the power grid. Further, the method includes determining, via a flicker compensation device, a flicker compensation parameter as a function of the one or more operational parameters. Moreover, the method includes determining, via the controller, a net reactive current command for the rotor as a function of the flicker compensation parameter and the nominal reactive current command.
