Gamesa says the G10X-4.5MW turbine has a 128m diameter rotor on 120m tower made of cement and steel. It claims the cost of installing the turbine is similar to that of a 2MW machine.
The Spanish manufacturer is also launching the G128-4.5MW turbine. Innovations to the G128 include:
- Innoblade. A blade that has been divided into sections allowing it to be easily transported. It also includes new aerodynamic features minimising noise.
- Multismart. A turbine control system modulating the pitch of each blade, reducing vibration and lessening load.
- ConcreTower. A tower made of steel and concrete with the aim of reducing costs and facilitating transportation.
- Flexifit. A crane coupled to the nacelle that can hoist or lower components such as the drive train or generator.
- GridMate. A permanent magnet synchronous generator using a full converter, "to guarantee the compliance with grid connection regulations".
Additionally Gamesa has designed an online forecasting service dubbed the ‘Mega' system, which provides customers will information on conditions at their wind farms.
The system provides seven-day forecasts by the hour of wind conditions. Gamesa claims the service will aid wind owners plan maintenance and mitigate financial risks associated with variations in the weather.
