1 V47-660 kWPitch regulated wind turbine with OptiTip and OptiSlip One or two generatorsThe standard V47-660 kW is delivered with a single generator, which is highly efficient in the vast majority ofwind conditions. A two-generator version is also avail-able, containing a second, smaller generator for use inwind speeds as low as 7 m/s. The result is a lower soundlevel where it is most needed, as well as more efficientexploitation of modest wind pitch with OptiTip As with all other Vestas turbines, the V47-660 kW turbineis equipped with microprocessor-controlled OptiTip pitch regulation, ensuring continuous and optimal adjustment of the angles of the blades in relation to theprevailing wind.

2 The OptiTip system makes it possibleto find the best solution to the often contradictory requirements for high output and low sound levels,depending on the The V47-660 kW turbine features the unique generatorprinciple OptiSlip , which allows both the rotor and thegenerator to vary their RPM by up to 10% to cope withviolent gusts of wind. In addition to reducing the loadon various parts of the turbine, the OptiSlip system alsoensures an appreciably better power protectionThe V47-660 kW turbine is equipped with Vestas Light-ning Protection, to protect the entire turbine from thetips of the blades to the bladesVestas always measures and tests all new products downto the smallest detail before releasing them to the market.

3 The flexible blades underwent a 6-monthdynamic distortion test under extreme loads morethan they would normally be exposed to in their 20-year service lives. The maximum loads and outwarddistortion of the blades were then checked in a statictest. The blades passed all the tests and now make anappreciable contribution to the efficient production ofthe V47-660 kW PerformanceWe spend many months testing and documenting theperformance of the Vestas turbines. When we are finallysatisfied, we run one last check by allowing an independ-ent organisation to verify the results. This is standardpractice at Vestas a procedure we call Proven Perform-ance. It is our guarantee that your Vestas turbine meetsthe very highest requirements for energy production,availability factor, power quality and sound Blade2.

It is not, although it is no more than a few yearssince this turbine was launched as theVestas genuine innovation when it was intro-duced in 1997, the V47-660 kW bladedesign set new standards, but the turbine asa whole, with its futuristic design andinnovative technology, became a model forthe giant turbines that have since begun toroll off the production , the V47-660 kW model remains a popular turbine that exploits the power of the wind reliably and efficiently.
