System for generating electrical power
First Claim
1. A system for generating electrical power, comprising:
- a turbine, mechanically connected to a generator, the generator being electrically connected via a converter and a multiphase transformer to a load, wherein at least two counter-connected switching devices of the converter are assigned to each phase of the transformer, the transformer including two winding arrangements in a star connection on the side facing the converter, each of the windings of the first winding arrangement is connected to the switching devices belonging to one phase and switched in one direction, each of the windings of the second winding arrangement being connected to the switching devices of one phase and switched in the opposite direction, and the star points of the two winding arrangements being connected to each other via a direct current choke.

Abstract
Described is a system for generating electrical power, which system includes a turbine that is mechanically connected to a generator, which in turn is connected via a multiphase transformer to a load. In at least one embodiment, at least two counter-connected switching devices of the converter are assigned to each phase of the transformer. The transformer is provided on the side facing the converter with two winding arrangements in a star connection. Each of the windings of the first winding arrangement is connected to the switching devices belonging to one phase and switched in one direction. Each of the windings of the second winding arrangement is connected to the switching devices belonging to one phase and switched in the opposite direction. The star points of the two winding arrangements are connected via a direct current choke.
