A 3-MW turbine features a 116-m rotor diameter for IEC Class IIa wind sites. Acciona Windpower says the wind class upgrade on the AW3000/116 turbine delivers a leading power curve and the best cost of energy at sites with medium wind speeds, while also performing exceptionally well at almost any site. ACCIONA Windpower will feature the AW3000/116 turbine at the upcoming American Wind Energy Association (AWEA) Windpower 2011.
“The AW3000/116 is an exciting evolution of the company’s 3MW platform. By maintaining the same best-in-class features while upgrading to IEC Class IIa sites, this turbine will deliver a superior power curve in almost any site condition – making it one of the most versatile wind turbines in the world,” said Joseph Baker, CEO of ACCIONA Windpower North America. “Enhancing our largest rotor to suit windier sites, while introducing the option for taller towers, makes our turbines more productive and an overall better value for customers.”
Multiple standard tower height options are offered in steel and concrete, including a 120-meter concrete tower, which will transform average sites into more competitive sites by capturing the better wind resource at higher heights. The company has over five years of experience with concrete towers having built over 80 wind turbines with them.
The company says the turbine is designed for long-term performance, reliability, and safety. These turbines have a global average fleet availability of more than 98%. The entire portfolio of 1.5MW and 3MW wind turbines provide maximum performance throughout the life of the project and at an investment level that ensures customers can deliver on their bottom line.
A few turbine features include:
- Generation at 12kV (compared to 690kV), which may eliminate the need for step-up transformers in small projects, resulting in significant customer savings
- Double-bearing support on the main shaft to reduce bending loads on the gearbox
- Hydraulic pitch control to provide safe and reliable blade pitching in all wind environments
- Six-pole, double-fed induction generator for improved voltage and frequency stability
- Advanced grid integration
