Abstract: A wind turbine is provided. The wind turbine includes a generator, an output thereof being connectable to a power grid via a power transmission path, the power transmission path comprising a generator side converter coupled to the output of the generator, a grid side converter coupled to the power grid, and a DC link coupled between the generator side converter and the grid side converter. For diverting the generator power, a load dump arrangement is provided which includes at least one resistor, a plurality of switches, and a plurality of electrical connections which electrically connect the at least one resistor to the output of the generator and across the DC link via the plurality of switches. One common and configurable load dump is used for both converter system failures and grid failures. As compared to two separate load dumps for converter failures and grid failures, the single load dump will require a smaller space for a wind turbine. Thus, the weight and size of the power converter system may be reduced.

Abstract: A method of operating a wind turbine is disclosed, the wind turbine comprising a power generator, a machine-side converter connected to the power generator, a line-side converter connected to a power grid through associated power components, and a DC-link connected between the machine-side converter and the line-side converter. The method includes monitoring the power grid for overvoltage events, and upon detecting an overvoltage event: (1) disabling active operation of the machine-side converter and the line-side converter, (2) enabling an AC load dump connected between the machine side converter and the power generator in order to dissipate power output from the power generator, (3) waiting for a waiting period, and (4) enabling active operation of the line-side converter and the machine converter when the overvoltage event ends within the waiting period.
