  • Electric circuit for generating electric power
    Patent number: 9190943
    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.

  • Method and circuit for testing a power producer or a power consumer which can be connected to a power grid
    Patent number: 9075116
    Abstract: Described is a method for testing a power producer or a power consumer that can be connected to a power grid. The power producer or the power consumer is connected to a terminal point. A converter circuit is provided for influencing a voltage that is present at the terminal point. The converter circuit is connected via a transformer to the terminal point. In at least one embodiment, a series connection is configured with a choking coil and a first switch and connected to the terminal point. In a time coordinated manner, the first switch is initially closed and the converter circuit is influenced such that the voltage has the desired value at the terminal point, whereupon the second switch is then opened.
