WIND PRODUCT SOLUTIONS Haliade™ 150-6MW Offshore Wind Turbine Alstom, one of the most trusted names in power generation, offers a new generation, high yield offshore wind turbine. Uncompromising on reliability and designed for ease of installation, the turbine lowers the cost of offshore energy. High yield, uncompromising reliability Building upon its ALSTOM PURE TORQUE® technology for drive train reliability, Alstom has developed an offshore 6MW direct-drive wind turbine suitable for all offshore conditions. Proven technology and innovation are combined to deliver market-leading cost efficiency. The turbine incorporates dedicated offshore technology in collaboration with some of the industry’s leading component suppliers. There can be no compromises on a power-generating product that operates in the industry’s most challenging environmental conditions. 2012 2013 2014 First onshore First offshore installation installation Technical overview The Haliade™ 150-6MW is a three-bladed upwind wind turbine operating at variable speed with a 150m diameter rotor and a rated power of 6MW. The turbine has been designed following Class I-B specifications of the standards IEC-61400-1 / IEC-61400-3. It is suitable for sites with a reference wind speed of 50m/s (10-minute average) and a 50-year extreme gust speed of 70m/s (3-second average). The Haliade™ 150-6MW is equipped with a direct-drive permanent magnet generator and three identical full-power converters operating at 900V. This voltage can then be increased by means of a transformer included in the turbine. The inverter, transformer, switchgear and low voltage electrical distribution cabinet are located at the tower base. A distribution cabinet in the nacelle supplies the pitch, the yaw and the cooling fans and collects signals from the sensors. The entire wind turbine is air-cooled and pressurised. Construction materials and protection treatments are specifically designed for offshore environments. Heat exchangers and pressuring units prevent salty air entering while dehumidifiers prevent corrosion of components inside the wind turbine.

Robust, simple and efficient Robust – with ALSTOM PURE TORQUE® The turbine features an innovative electromechanical layout combining Alstom’s unique and proven rotor support technology with a direct-drive permanent magnet generator, providing outstanding reliability of the turbine’s drive train. The PURE TORQUE® design protects the generator and improves its performance by diverting unwanted stresses from the wind safely to the turbine’s tower through the main frame. The design separates the turbine rotor and generator to ensure that only turning force – torque – is transferred to the...
