Wind turbine has rotor hub with multiple rotor blades, where energy storage is arranged in rotor hub for supplying electrical power to rotor blade adjustment angle drives

摘要

The wind turbine has a rotor hub with multiple rotor blades. Multiple rotor blade adjustment angle drives are arranged in the rotor hub, where each rotor blade is assigned a rotor blade adjustment angle drive. An energy storage (10) is arranged in the rotor hub for supplying electrical power to the rotor blade adjustment angle drives. A heating device has multiple heating elements, where an accumulator group (14) is assigned a heating element. An independent claim is included for a method for heating an energy storage arranged in a rotor hub of a wind turbine.
