Windenergieanlage und Energieübertragungseinrichtung für eine Windenergieanlage |
摘要 |
A wind energy plant has a rotor with a rotor hub mounted on a pod and a plurality of rotor blades adjustable by corresponding electrical drives. An electrical generator is connected to the rotor for supplying energy to electrical loads arranged in the rotor hub. A primary part of a rotary transformer arranged concentric to a rotor bearing is connected to the pod and a secondary part of the rotary transformer is arranged in the rotor hub and co-rotates with the rotor hub. A first frequency converter is connected between the primary part and a supply voltage source for generating a high-frequency field voltage from a low-frequency supply voltage, and a second frequency converter is connected between the secondary part and the electrical loads for generating a low-frequency load voltage from a transformed high-frequency field voltage. |
