Abstract
The present invention relates to a method and to a device for adapting the alternating current generated by a generator () and the alternating voltage generated by a generator () to a grid (), whereby the generator () has at least one excitation coil (). The power fed into the grid () can be flexibly adapted while entailing low switching losses in that a static frequency converter () is employed for the adaptation between the generator () and the grid (), and in that, in order to control the power fed into the grid (), means () are provided with which, on the one hand, the strength of the excitation field generated by the at least one excitation coil () is regulated and, on the other hand, the phase angle between the frequency converter voltage and the generator or grid voltage is appropriately controlled.
