发明名称 Wind turbine
摘要 A wind turbine is provided. The wind turbine includes at least one generator adapted to generate electric power and a plurality of electrical converter units adapted to convert electric power generated by the generator and electrically connectable or connected to the generator and to a utility grid. The generator includes a stator being segmented in stator segments. Each stator segment includes a plurality of stator windings. The stator windings of the respective stator segments are divided into at least a first and a second group of stator windings with each group including at least one stator winding. Several or all first groups of stator windings are electrically connected to a first electrical converter unit and several or all second groups of stator windings are electrically connected to a second electrical converter unit.

主权项 1. A wind turbine, comprising: at least one generator adapted to generate electric power, and a plurality of electrical converter units adapted to convert electric power generated by the generator and electrically connectable or connected to the generator and to a utility grid, wherein the at least one generator comprises a stator that is segmented in stator segments, wherein each stator segment comprises a plurality of stator windings, wherein the stator windings of the respective stator segments are divided into at least a first group of stator windings and a second group of stator windings, wherein each stator winding of a stator segment of the first group has a common phase angle with a stator winding of a stator segment of the second group and the common phase angle is different from the phase angle of any other stator windings of the same stator segment, each of the first and second groups comprising at least one stator winding, and wherein several or all first groups of stator windings are electrically connected to a first electrical converter unit and several or all second groups of stator windings are electrically connected to a second electrical converter unit, wherein groups of stator windings of different stator segments that are electrically connected to the same electrical converter unit are electrically connected with each other by way of a connection line to respective electrical sides of the stator windings not connected to the electrical converter unit.
