HALIADE™ 150-6MW ROBUST, SIMPLE, EFFICIENT The Haliade™150-6MW is a three-bladed wind turbine. Using 73.5m turbine blades, the 150m diameter rotor combined with 6 MW rated power maximizes the capture of energy. The generator is key component of the wind turbine because it is the component in charge of generating the electricity. The Haliade™150-6MW is equipped with a direct-drive permanent magnet generator: with no mechanical gearbox coupled to the generator, the turbine consists of fewer rotating parts, which increases reliability, maximises turbine availability and reduces maintenance costs. NACELLE SECONDARY COOLING SYSTEM HUB The hub supports the rotor blades and houses their pitch assembly. It is designed in such a way as to provide easy, direct access for technicians working from the nacelle. ROTOR BEARINGS The rotor bearings directly transfer the unwanted load on the rotor towards the main structure, bypassing the drive train. A helicopter winching area allows for quick rescue in case of emergency at sea. SLIP RINGS The yaw system makes it possible to pivot the nacelle and thus orient the wind turbine in the optimal direction, i.e. facing into the wind. PITCH The pitch system makes it possible to control the blade angle, which optimises the area exposed to the wind and the speed of rotation to, ultimately, increase the yield. MAIN FRAME Made of cast steel, the main structure houses the nacelle inside the central frame, and the PURE TORQUE® system inside the front frame. ALSTOM PURE TORQUE® This technology was exclusively developed by Alstom and is found in all of its wind turbines. It protects the drive train from unwanted wind buffeting by deflecting it towards the tower. The PURE TORQUE® system improves turbine efficiency and durability. Built upon ALSTOM PURE TORQUE® proven technology for drive train reliability, Alstom has developed a new generation, 6 MW direct drive offshore wind turbine. Suitable for all offshore conditions -uncompromising on reliability-, the turbine will deliver a leading cost of offshore energy while supplying electric power for up to 5,000 households. INTERMEDIATE FRAME ELASTING COUPLING Key element of the ALSTOM PURE TORQUE® principle which includes a patended coupling system with rubber elements that avoid any undesired load towards the generator. A hydraulic system embeded in the rubber parts guarantees that misalignements between main rotor and generator rotor are affecting the bearings configuration. FRONT FRAME TOWER The Haliade™150-6MW tower is 100m-high and made of tubular steel.
