Renewable Energies and Smart Grid » Wind

Wind energy captures the natural wind and converts the air’s motion into mechanical energy usually for electricity production and this mechanism is referred to a wind-electric turbine. The turbine blades are normally designed to capture the kinetic energy in wind and when start moving, they spin a shaft that leads from the hub of the rotor to a generator that turns the rotational energy into electricity. Here also De Lorenzo has developed many trainers of different levels and one in particular is aimed to a very high level that takes into account the operations of doubly fed induction generator (DFIG) and the fault ride through complete with SCADA software. For the basic level, a case containing the necessary modules has been designed to learn the first steps of this technology. For the medium level, a hybrid trainer can satisfy both the technicians and the installers (a kit based on sub-modules for solar and wind at the same time). For the high level, different configurations are proposed such as off-grid and on-grid with drive motor (DC or stepper) for indoor use and a trainer tunnel where it is possible to change the flow of the air that reaches the wind turbine performing experiments with or without load. This latter level is also supplied complete with software for data acquisition and processing.They are dedicated to schools, high schools and first years of university according to the level.

DL WIND-B

SAVONIUS TURBINE

This turbine belongs to the category of resistance turbines, where the resistance to the force of the wind causes the rotation of the axis.
The greatest handicap of vertical axis turbines, which limits their performance, consists in the fact that a part of them will rotate in the opposite direction to the wind and a part in favor.
The Savonius turbine, to avoid this problem, is made of two half-shells (in the simplest version) which are not joined to the rotor of the turbine, but arranged so that a part of the half-shells lets the thrust air flow also through the upwind part.

DL VAWT

GIROMILL TURBINE (Savonius – Darreius)

This turbine belongs to the category of lift turbines.
The lift is the force that acts on a wing profile because of a pressure difference, given by the different speeds which takes the fluid when "lapping" the surfaces of the profile.
With the increase of the speed of rotation, the upwind blade acts as a brake and limits and stabilizes the speed of rotation.
Another important aspect to be monitored is related to the resistances that oppose the start of the movement.
It may happen, in fact, that these are greater than the forces of rotation impressed by the wind to the machine.
This is why some wind turbines of this type can be started only with strong winds or through auxiliary starting motors.
