Abstract: A converter including a converter control for a wind turbine and a chopper, wherein the converter control includes a dynamic limit value which is allowable for a first tolerance time and a static limit value of the converter. Furthermore, an overcurrent module is provided which includes a limit value expander which is designed to increase the static limit value by a portion of the difference from the dynamic limit value as additional current, and a dynamic module which interacts with the limit value expander in such a way that overcurrents between the static limit value which is increased by the additional current and the dynamic limit value are routed in a first stage to the converter and in a second stage at least partially to the chopper, wherein a switch is made to the second stage after a second tolerance time.

Abstract: A wind turbine comprises a wind rotor, a generator driven by the wind rotor, a converter, wherein the generator and the converter generate electrical energy output via a connecting line with an inductively acting line reactor to a grid, and an overvoltage protection device comprising a plurality of different active modules, which are designed in such a way that they each effect, in different ways, a reduction in the voltage at the output of the converter, a switching matrix, which connects and disconnects the different active modules, and a selector comprising an overvoltage classifier, which is designed to select a predetermined stage depending on the overvoltage and to actuate the switching matrix in such a way that successive ones of the active modules are disconnected, wherein the overvoltage classifier defines a plurality of overvoltage ranges by virtue of in each case the selector setting different switching groups.
