Modeling, Control and Design of Wind Energy Systems an der TU München

• Horizontal-axis three-bladed upwind variable-speed wind turbine
• Pitch control
• Various typologies depending on generator type, location of main
bearings, gearbox, brake, …

direct driven do not need a complex gearbox but generate less energy due to low speed

beyond reach of wind power technology: policy uncertainties, permitting and approval time

Affected by technological innovation: social acceptance, environmental impact

Noise

Recycling

local climate

wildlife

Visual impact

aerodynamics

materials

active smart blade

electromechanical conversion

contruction technilogy

- dimensions (need of large volumes but low cost materials)

- reliability/maintenance: performance with simplicity and robustness

- key design objective: low CoE for wind energy (Cost of Energy)

- rotating components

Increase AEP (Anual energy production)

- higher tower -> higher wind speed because of vertical shear

- large swept area -> larger power capture

- improved capacity factor -> lower CoE

• huge available resouces
• improved social acceptability
• lower environmental impact
• scale/ logistics (production more and more at habour)
• potential for reduces LCOE

• stationary flow
• constant mass flow rate along stream tube
• incompressible and inviscid flow
• actuator disk

Main goal is to reduce CoE -> one of the most effective ways is to increase AEP

With a increased diameter/ increased swept area 

• the power capture is larger
• the wind speed is higher due to a higher tower

1500 in Europe -> horizontal axis, furling blades (Rollschaufeln), Yaw control
