Abstract
Provided is an arrangement for producing electric energy, including: a generator having plural winding sets; plural converters each connected to one of the winding sets; at least two transformers, each connected at a low voltage side to output terminal of at least one converter; and a control portion connected to control the converters.
Claims16
An arrangement comprising:
- a generator having a plurality of winding sets, the generator driven by a prime mover;
- a plurality of converters, each converter connected to one of the plurality of winding sets;
- at least two transformers, each transformer having a low voltage side connected to an output terminal of at least one of the plurality of converters;
- a measurement module adapted to measure voltage values at the low voltage sides of each transformer;
- a processor adapted to derive an average voltage value as an average of the voltage values associated with the at least two transformers;
- and
- a control portion connected to control the plurality of converters based on the average voltage value.
