Wind Turbine - Energy Harvesting

Technology Roadmap Sections and Deliverables

Team 3 is to present a "level 2” roadmap of Wind Turbine Generators. The following code is the identifier.

• 2WTG - Wind Turbine Generator

Roadmap Overview

Wind turbines are used to harvest kinetic energy from the wind and transform that energy into electricity. A rotor, typically with three airfoil blades, rotates using the force of lift. A system of gears is used to transfer rotational energy of the hub to a high-speed shaft which feeds into a generator. The generator then utilizes the rotational energy to generate electricity and deliver it down the tower through a cable. An anemometer and weather vane are used to determine the wind speed and direction. The data they collect is processed in the control box, which then adjusts the pitch of the blades and yaw of the nacelle for optimal operating conditions. Wind turbines can be assembled on land or water and usually generate energy proportional to their size.

Design Structure Matrix (DSM) Allocation

The 2-WTB tree in the upper right corner displays some of the key components of a wind turbine, that when individually improved, enhance the overall performance and figures of merit of the wind turbine. This tree also exposes the purpose of the wind turbine itself, which is to aid in overall electricity generation. Wind turbines can be combined into wind farms which together can replace a carbon releasing power plant. The tree can then be expanded into a more complex matrix that shows how most of its components are interconnected. Many of the parts are connected physically, some transfer energy, and others share information.
