摘要： 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.

The method may also include performing a statistical analysis of the data relating to one or more parameters of the one or more electrical components. Further, the method includes predicting future behavior of the electrical component(s) based on the statistical analysis. Moreover, the method includes determining set points for the electrical component(s) using the predicted future behavior. In addition, the method includes operating the wind turbine power system at the determined set points for the electrical component(s) so as to optimize at least one characteristic of the electrical component(s).

摘要： An apparatus and method for improved current shunt sensing in an electrical system, such as a renewable energy electrical system, is disclosed. A current shunt 200 according to aspects of the present disclosure includes a conductive portion 220 that is placed in series with an electrical system. The current shunt includes a sensing element 230 that is used to measure the voltage across the conductive portion 220 of the current shunt 200. The sensing element 230 has an increased width relative to the width of the conductive portion of the shunt 200. The increased width of the sensing element 230 provides for improved current shunt sensing that results in more accurate voltage (and thus current) measurements across a wide range of frequencies.

摘要： Systems and methods for regulating voltage in a doubly fed induction generator (DFIG) system 200 are provided. More particularly, the voltage of the auxiliary power feed 170 in a DFIG wind turbine system 200 can be regulated by outputting reactive power from a power converter 130 to a reactive element 172 coupled between the auxiliary power feed 170 and a stator bus 122. The reactive element 172 can include a winding of the transformer 130 used to couple the wind turbine system 200 to the electrical grid 180 and/or an inductive element 172 coupled between the output of the power converter 130 and the stator bus 122. The voltage of the auxiliary power feed 170 can be maintained within a reduced operating range while an increased operating range can be provided for a wind turbine system 100.

摘要： Embodiments of the invention can provide systems, methods, and apparatus for converting direct current (DC) power to alternating current (AC) power. According to one embodiment, a system (200) for converting DC power to AC power is provided. The system (200) includes a DC power source (205) that provides a first DC power signal to a converter (215). Coupled to the converter (215) is a controller (230) for transforming the first DC power signal into a plurality of AC power signals. The controller (230) phase shifts at least one of the plurality of AC power signals and combines the phase shifted AC power signal with at least one of the other AC power signals to provide a second DC power signal. Once the second DC power signal is provided, the controller (230) converts the second DC power signal to an AC power signal.
