Sketch test site for wind turbines in complex terrain (c) WINSENT

WINSENT (Wind, Science and Engineering: a Test-Site)

With increasing use of windfarms for the production of electricity comes the need for optimization of these facilities. Fields for optimization include the mechanical properties of turbine and rotor blades, location of a wind turbine, maintenance, prevention of noise and hazards due to formation of ice of material fatigue. Hilltops are an interesting location for a wind park since the average wind speed is usually higher compared to the surrounding area leading to a greater power generation. However, the complex topography gives rise to questions due to wind gust intensity and variability of the wind direction. The wind loads associated with a turbulent wind field cause material stresses and may increase the maintenance cost of such a wind turbine while reducing its potential for power generation.

Key goals of the WINSENT project are:

  1. Building a wind turbine test-site in complex terrain
  2. Adaptation, development and validation of a chain of computer models for the simulation of the wind conditions ranging from the large scale weather down to turbulence at the rotor blades.
  3. Definition and erection of two wind turbines for scientific use.

Simulations of the wind conditions at the test site are performed at the IMK-IFU. Two masts with meteorological sensors are erected in front and behind a wind turbine. Data is gathered over an extended period to validate these simulations.
