摘要

The wind park has an accumulative network (2) and a set of wind energy plants (1), where each wind energy plant includes a generator driven by a rotor for producing electrical energy. The wind energy plant has an electrical connection by which the electrical energy is guided at a network-connection point (9). The plants are attached to the accumulative network by turbine transformers. A group (1A) of the plants has a separate swiveling transformer (5''') i.e. auto-transformer, that produces a swiveling phase to another group (1B) of the plants.
