概要

The Computer Controlled Wind Energy Basic Unit, "MINI-EEEC", is a small-scale unit designed to study wind energy and the influence of some factors on its generation.

This unit consists of a transparent tunnel, a wind turbine with rotor to place up to six blades and a computer controlled variable speed axial fan.

The air speed is varied by changing the rotational speed of the axial fan and a sensor allows for measuring that air velocity.

This fan generates the required air flow to make the rotor of the wind energy unit work. The generator converts the kinetic energy of the rotor into electric energy. The rotational speed of the wind turbine can be measured with a sensor.

The unit includes a DC load module with LEDs, a rheostat, a DC motor, a load selector and switches to select the type of load. Thus, the wind turbine may work in open circuit or connected to LEDS, to a rheostat or to a DC motor.

A voltage and current sensor measures the voltage and current provided by the wind turbine in order to determine the power.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
