The wind turbine WTN 500 is a pitch-controlled turbine with complete variable speed for operation parallel to the public grid. The rated output of the plant is 500 kilowatt; the rotor diameter is 48 meters.
The rotor has three blades and is arranged in upwind position of the tower. Yawing into the wind is achieved by two electrically driven yaw systems. You can choose between a 40m or 50m tubular and a 65m lattice tower.The mechanical concept of the nacelle is based on a three-point-fixing of the main bearing together with the main gear unit and a two-generator system.
The WTN 500 operates with variable speed. The rated power of both asynchronous generators comes to 280 kilowatts each. Two frequency converters are installed to feed the electrical power to the grid.
