Highlights of the design:

• Lower capital costs through a more simple lightweight design.
• Very low maintenance costs through reliability, simple design, and roomy nacelle interior.
• Greater reliability through lower loading of critical parts.
• Faster installation and lower installation costs through reduced weight, reduced crane time, and ground-based assembly.
• The N1000 is Det Norske Veritas (DNV) certified.
   

The N1000 is Nordic Windpower’s 1-MW turbine designed both for large windfarms and for smaller community wind deployments. The design and development emphasizes simple, lightweight construction, delivering low installation and operating cost, world-class reliability, and ease of maintenance. The unique “flexible design” implements a teeter-hinged hub, planetary drive train, damped yawing system, and a lightweight “over-critical” tower configuration. The end result of this design approach allows for more movement and flexibility to dissipate wind fatigue loading, while dramatically reducing material and construction costs.

N1000 Overview

Light and flexible design, greater reliability, and lower cost.

The N1000 1-MW turbine implements a lighter and less-complicated design than traditional wind turbines, delivering significantly lower overall cost of energy and greater reliability.

Principal ideas of design

In turbine design, the amount of construction material is proportional to the loads that have to be sustained. The N1000 design minimizes fatigue loads during normal operation. The revolutionary “flexible design” for the blade, hub, yaw drive, and tower evens out the impact of turbulence and wind shear. Flexible design implements proprietary engineering through very extensive simulations that precisely calculate the eigenfrequency oscillations of the entire system and designs around high component loads. The result is a turbine lighter and more reliable than much heavier and more expensive "Danish topology" turbines.

The turbines deployed in the field have performed at 98% reliability, with no major component failures, over more than 100,000 hours of operation, in normal and extreme wind conditions.
