Abstract
An electric circuit is described for generating electric power. In this circuit, an asynchronous generator includes a stator and a rotor. On the stator side, the asynchronous generator is coupled to a power grid. The rotor current flowing to the rotor of the asynchronous generator can be measured. A control device is designed such that, in case of a fault in the power grid, the stator current flowing to the stator of the asynchronous generator is calculated from the measured rotor current as a function of parameters of the asynchronous generator.
