“EEEC”is a laboratory-scale unit designed to study the eolic energy and the influence of some factors on this generation.
The axial flux fan introduces air in the tunnel. The air speed sensor let us to measure air speed. It is possible to know, in real time, the value of voltage an current given by aerogenerator, measured before and after the regulator. We can measure the speed of the air, with a sensor placed in the tunnel, and also know the rotational speed of the aerogenerator (r.p.m.). There is one temperature probe before the rotor, in order to know the temperature for density calculation. This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), including: Control Interface Box + Data Acquisition Board + Computer Control and Data Acquisition Software, for controlling the process and the parameters involved.
