The V112-3.0 MW is a hard-working, reliable turbine designed for low and medium wind speed sites onshore anywhere around the world. These are the areas that comprise tomorrow’s biggest market for wind power plants. The V112-3.0 MW can generate more power than other turbines in the 3 MW class. It offers an exceptional rotor-to-generator ratio for greater efficiency and delivers unsurpassed reliability, serviceability and availability under all wind and weather conditions – setting a whole new standard for turbine performance and efficiency.
Advanced power electronics conversion
Advanced power electronics conversion ensures stable and scalable output from the turbine. Combined with a flexible operations strategy, advanced power electronics conversion allows you to increase power production by temporarily increasing the power output of the turbine in favorable conditions.

The new nacelle design is a good example of innovative technology with decades of experience. The power converter is integrated into the nacelle floor, which provides more working space and makes it easier to service the components. Significantly more floor space is just one of the features that make service and maintenance both faster and easier. The design makes smarter use of space while also setting new standards for ergonomics and safety in the nacelle. Essential tasks can be completed effectively without compromising
safety. There is plenty of room for handing all spare parts, and the main components can be lifted in with ease. On sites with limited accessibility, it can often be a good idea to install nacelle components with the help of Vestas’ innovative tower crane, which does away with the need for expensive mobile cranes.
Load reduced operation
Load reduced operation provides extra security at complex sites, where narrow sectors with extreme gusts and other abnormal wind conditions can occur. Load reduced operation enables the turbine to automatically protect itself against needless wear, which can damage the turbine and shorten the service life of some components.
Main component preheating
The cooling system in the V112-3.0 MW is also used for preheating, which prevents condensation. Primary components such as the generator, the gearbox, the converter and the blade hydraulic system are heated from inside by means of hot water in the cooling systems when the turbine restarts after a production stop in cold climates.

Automatic lubrication of the blade bearings, the yaw system, the main bearing and the generator boosts reliability while reducing the frequency of service calls.
Options
The V112-3.0 MW is available with a number of special options that can be provided at the customer’s requests. These options include:
· Condition monitoring system
· Aviation markings on the blades
· Aviation lights
· Smoke detectors
· Fire extinguishing system in nacelle
· Company logo
· Low temperature operation to –30°C
· Ice detection system
Can be installed almost anywhere in the world
Even though the V112-3.0 MW is a mass-produced wind turbine for low and medium wind speed sites, it complies with all the standard transportation requirements. Even with its 54.6-metre blades, the V112-3.0 MW can be transported to most sites in the world without being subject to special fees and restrictions that can delay or increase the cost of wind power plant construction.
A giant stride in aerodynamics
Vestas is famous for designing and producing some of the world’s lightest and most effective blades – blades that deliver the greatest possible output while causing the least possible loads to the turbine. With the groundbreaking 54.6-metre blades on the V112-3.0 MW, Vestas has taken another giant stride in aerodynamics. Although these blades have the same width as our 44-metre blades, they sweep an area that is 55% greater to deliver considerably higher output. Finally, the blades are designed to be less sensitive to dirt, resulting in better performance at sites affected by salt, insects or other particles in the air.

The V112-3.0 MW is a quiet turbine even during power optimised operation, but it is even quieter during low-noise operation. The turbine can be operated in configurable modes that keep within defined decibel ranges, without having a significant effect on productivity. This makes the V112-3.0 MW ideally suited for use anywhere in the world where sound-level limits are in force.
Verified component lifetime
At the Vestas Testing Centre and Technology R&D, engineering experts and technicians use state-of-the-art testing methods to ensure that all components and systems meet our standards for safety, performance and reliability throughout their 20-year service life. These tests push the components beyond their specifications. One method is known as Highly Accelerated Life Testing, where some of the testing is conducted in a HALT
chamber. Extreme fluctuations in temperatures combined with heavy vibrations are just some of the stress tests the components are subjected to here. This enables Vestas to identify and address design flaws long before the turbines reach the market.
Service and maintenance
Vestas has service centres around the globe and we are able to cover your every need, from simple cleaning and planned maintenance to emergency call-outs and on-site inventories customised for your turbines.
Project management for effective plants
The better your turbines fit your wind site, the more profitable your plant will be. That’s why Vestas offers to take on project management from the initial wind measurements to complete installation of the wind power plant. More than 30 years of international experience and local expertise enable us to complete:
· Wind and site studies
· Designing the wind power project
· Selecting wind turbine types
· Installing the wind farm
· Servicing and maintenance throughout the turbine’s service life
· Monitoring and remote troubleshooting.
