With more than 3,700 of these turbines erected around the globe, the V52-850 kW is a tried-and-tested piece of technology – rigorously proven in the field, robustly constructed and with an enviable track-record. Investors can be confident its easily transportable design features make it an ideal choice for remote areas or sites with challenging access. Efficient technology extracts maximum energy The efficient generator harvests maximum energy from slow or variable rotations, storing excess energy in rotational form to maximise the potential power of gusty conditions. The turbine rotor speed can vary between 14 and 31rpm to amplify the power output across a range of wind conditions. Lower peak loading reduces strain on the gearbox, blades and tower, helping to keep breakdowns and maintenance periods to a minimum and delivering a greater return on investment.2011-06-14T15:18:31+02:00http://nozebra.ipapercms.dk/Vestas/Communication/Productbrochure/V52850kW/V52850kWUK/?Page=3http://nozebra.ipapercms.dk/Vestas/Communication/Productbrochure/V52850kW/V52850kWUK/?Page=3Wind. It means the world to us.™ Wind is all we do. We are relentlessly committed to the success of wind as a source of energy for the world, providing everything you need to succeed in your wind power ambitions. Peak Performance for medium and high wind sites2011-06-14T15:18:31+02:00http://nozebra.ipapercms.dk/Vestas/Communication/Productbrochure/V52850kW/V52850kWUK/?Page=4http://nozebra.ipapercms.dk/Vestas/Communication/Productbrochure/V52850kW/V52850kWUK/?Page=4Proven technology optimises output across the wind spectrum The V52-850 kW is a reliable investment choice, ensuring maximum yield from IEC IIA and IEC IA medium and high wind speed locations.

The microprocessors in our unique pitch regulation system constantly adjust the angles of the blades to suit the prevailing wind. The same system also keeps audible sound levels within local regulations, widening the scope of sites appropriate for a wind farm. Six different tower heights add further flexibility to the V52-850 kW, making it equally suitable for both populated and remote sites. The technology used in the V52-850 kW – including the slim blade design – is also used in several of our other turbines. All key components have been rigorously tested in-the-field and across thousands of existing installations – so you can be sure of dependable and productive technology. Cheaper to transport, quicker to install The light weight of the V52-850 kW minimises construction and transportation costs. Inspired by the success of the V52-850 kW, similar weight regimes have been rolled out across other turbines in our range, allowing us to further optimise our installation processes. The V52-850 kW features a compact style of blade transportation which allows the safe transportation of three blades at one time using existing trucks and cranes. This makes installation quicker and minimises transportation costs.2011-06-14T15:18:31+02:00http://nozebra.ipapercms.dk/Vestas/Communication/Productbrochure/V52850kW/V52850kWUK/?Page=6http://nozebra.ipapercms.dk/Vestas/Communication/Productbrochure/V52850kW/V52850kWUK/?Page=6Designed for reliability and high-performance Advanced OptiSpeed® technology for peak performance Our V52-850 kW turbines feature OptiSpeed® generator to vary rotor speeds between 14 and 31 rpm, automatically responding to the prevailing wind. OptiSpeed® boosts annual energy production by exploiting the rotations from slow and variable conditions and storing the excess energy. With rapid synchronisation, reduced harmonic distortion and less flicker, it ensures a better quality power output, consistently keeping sound levels and component strain to a minimum.2011-06-14T15:18:31+02:00http://nozebra.ipapercms.dk/Vestas/Communication/Productbrochure/V52850kW/V52850kWUK/?Page=7http://nozebra.ipapercms.dk/Vestas/Communication/Productbrochure/V52850kW/V52850kWUK/?Page=7Control system – Synchronisation of generator to the grid – Operation of turbines during various fault situations Generator – Doubly fed generator – Equipped with wound rotor and slip rings – Connected to Vestas converter system – Air cooled Drive train – Forged main shaft – Separate main bearing housing with two main bearings – One planetary stage plus two helical stages gearbox Yaw system – Three-step planetary and one-step worm gear unit with motor brake and torque limiter – Two yaw gears Blade – Glass fibre reinforced epoxy – Slim blades with efficient wind utilisation2011-06-14T15:18:31+02:00http://nozebra.ipapercms.dk/Vestas/Communication/Productbrochure/V52850kW/V52850kWUK/?Page=8http://nozebra.ipapercms.dk/Vestas/Communication/Productbrochure/V52850kW/V52850kWUK/?Page=8VestasOnline® Business – putting you in control As a valued customer, you’ll benefit from VestasOnline® Business, our state-of-the-art Supervisory Control and Data Acquisition (SCADA) management system specifically designed for modern wind power plants.
