WIND PRODUCT SOLUTIONS Haliade™ 150-6MW Offshore wind turbine Alstom, a key player 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 reliability, Alstom has developed a 6 MW direct-drive wind turbine suitable for all offshore conditions. Proven technology and innovation are combined to deliver market-leading cost efciency. 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. TECHNICAL OVERVIEW A distribution cabinet in the nacelle supplies power and signals to pitch, yaw and cooling fans and collects signals from all system sensors. The Haliade™ 150-6MW is a threebladed wind turbine with a 150 m diameter rotor and a rated power of 6 MW. The turbine has been designed following Class I-B specications of the standards IEC-61400-1 / IEC-61400-3. It is suitable for sites with a reference wind speed of 50 m/s (10 minutes average) and a 50-year extreme gust speed of 70 m/s (3 seconds average). Alstom’s Haliade™ 150-6MW has been key in winning 3 projects for the installation of 240 wind turbines off the coast of France. This innovative technology helps drive down the cost of electricity and we believe this 6 MW turbine is positioned as the market reference in the eld of offshore wind worldwide. Béatrice Buffon, Deputy General Manager of EDF EN France The Haliade™ 150-6MW is equipped with a direct-drive permanent magnet generator and three identical full-power converters operating at 900 V each. This voltage is 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. 1st onshore turbine installation Power curve certication The wind turbine is air-cooled and pressurised. Construction materials and protection treatments are specically designed for offshore environments. Heat exchangers and pressuring units prevent salty air entering while dehumidiers prevent corrosion of components inside the wind turbine.
