Title:
WIND ENERGY PLANT AND ENERGY TRANSMISSION DEVICE FOR A WIND ENERGY PLANT
Document Type and Number:
WIPO Patent Application WO/2010/118914
Kind Code:
A3
Abstract:
The invention relates to a wind energy plant comprising a rotor having a rotor hub which is mounted on a gondola and a plurality of rotor blades which can be respectively adjusted by means of an electric drive device. An electric generator is connected to the rotor. A rotary transmitter is arranged concentric to the rotor bearing, which is provided to supply energy to a plurality of electric consumers arranged in a rotor hub. A primary part of the rotary transmitter is connected to the gondola. A secondary part of the rotary transmitter is arranged in the rotor hub and can be rotated therewith. Said wind energy plant also comprises a first frequency converter used to generate a high-frequency excitation voltage from a low frequency supply voltage which is connected between the primary part and a supply voltage source. The invention also relates to a second frequency converter used to generate a low frequency consumer voltage from a high frequency transformed excitation voltage which is connected between the secondary part and the electric consumers in the rotor hub.
