Acciona AW-1500 Wind Turbine from Acciona Windpower

Acciona Windpower offers the AW-1500 wind turbine. This variable speed 1500 kW wind turbine has a horizontal shaft and three blades. This wind turbine offers 12 kV voltages in 50 or 60 Hz frequencies.

For efficient operation in different types of wind conditions the AW-1500 wind turbine is offered with a rotor in 70, 77 and 82 m diameter sizes and blades in 34, 37.3 and 40 m lengths. The wide hub of this wind turbine is made of modular cast iron and houses a hydraulic pitch system to lock the blades during emergencies. The hub can be entered from nacelle for maintenance.

Blades of this wind turbine are made of fiberglass reinforced polyester or epoxy resin, covered with a special surface protection and are equipped with individual pitch system for blade regulation and control. The Nacelle of this wind turbine is made of fiberglass reinforced polyester. The nacelle houses a crane, a three phase asynchronous induction generator with wound rotor and startup by collector rings, a yaw system utilizing a gear ring integrated into the tower and four geared motors and an active hydraulic braking. This wind turbine is available in 60, 71.5 and 80 m heights with hubs made of tubular steel towers and in 80 and 100 m heights with hubs made of concrete towers. The control and power unit of this wind turbine incorporates an INGECON-W system for continuous optimization of power production in a wide range of wind speeds.

The AW-82/1500 model wind turbine offered by Acciona Windpower has a rotor of 82 m diameter and blades with 40 m in length to offer a swept area of 5,289 m². Each blade of the rotor weighs 5.780 kg. This wind turbine starts rotating at 3.0 wind speed and produces a nominal power of 1500 kW at 10.5 m/s speed with 16.7 rpm. For the purpose of protecting the blades from damage this wind turbine ceases its operations when the wind speed exceeds 20 m/s.
