文档介绍：Low Wind Speed Technology Phase I: Prototype Multi-Megawatt Low Wind Speed Turbine
General Electric Wind Energy, LLC
Project Description: Parametric design studies conducted by the . Department of Energy, the National Renewable Energy Lab-
oratory, and their subcontractors show that advanced wind turbine architectures offer significant cost of energy reductions relative
to current technologies. Cost of energy improvements could be realized concurrently along three separate avenues:
• Reduce costs and increase efficiencies with advanced ponents.
• Place turbines on innovative tall towers to partially negate atmospheric shear layer effects and augment energy capture.
• Enhance energy capture via larger rotor diameters and innovative rotor configurations.
These parametric studies indicate that several techniques can bined to make these improvements. Many, such as decreasing
drivetrain weight to make taller towers more cost effective and introducing novel rotor designs that decrease loads and allow
larger rotor diameters, are interrelated. Emerging control strategies, coupled with increased instrumentation, can help to cost-
effectively integrate these major elements.
Within this context, GE Wind Energy is developing an advanced prototype turbine to significantly reduce energy costs in low
wind speed environments. This effort will pursue an evolutionary path
