Wind power plants

Fundamentals of wind power plants

ET 210

The design of a rotor blade for modern wind power plants has to take into account both the aerodynamic properties and the mechanical load-bearing capacity. Blade profiles which have been optimised in extensive simulations are often used in order to satisfy the requirements of largescale wind power plants.

  • compact unit, experiments can be carried out without additional accessories

  • wind power plant with variable speed

  • adjustment of rotor blade and yaw angle

  • network capability: observe, acquire, analyse experiments via customer‘s own network

Wind power plant with rotor blade adjustment HM 170.70

HM 170.70, together with the HM 170 wind tunnel, allows you to demonstrate a wind turbine with rotor blade pitching and variable-speed generator. The wind turbine is connected to the wind tunnel. The axial fan in the wind tunnel has a variable speed and provides the air flow required for the experiments.

  • use as accessory for HM 170

  • wind turbine with variable speed

  • rotor blades adjustment angle adjustable via servo motor

  • network capability: observe, acquire, analyse experiments via customer‘s own network



Energy conversion in a wind power plant ET 220

In order to be able to use wind energy, the kinetic energy of the wind first has to be converted into rotational energy. The rotational energy can then be used in a generator to produce electrical energy. As with all energy conversion processes, losses have to be monitored in each separate step.

  • practical experiments in laboratory scale

  • with accessories ET 220.01 and ET 220.10 (available separately): operation under real wind conditions possible

  • network capability: observe, acquire, analyse experiments via customer‘s own network
