Abstract:
1. A method for controlling a static frequency converter, the method comprising: generating a first alternating voltage having a first frequency using a generator having at least one excitation coil; rectifying the first frequency using a switched rectifier so as to provide direct voltage in an intermediate circuit; converting the direct voltage in the intermediate circuit into a grid alternating voltage having a grid frequency using a switched inverter; regulating at least a strength of an excitation field generated by the at least one excitation coil using a regulator so as to control power fed into the grid; wherein control of the frequency converter in the rectifier is performed in such a manner that the frequency of the alternating voltage of the rectifier on a generator side is regulated to an essentially constant value of the first frequency, and wherein control in the inverter is performed based on a measured value of the direct voltage in the intermediate circuit.
