ATENG 11869 — Wind Energy Unit
Anodized aluminum frame and panels made of painted steel.
The unit includes wheels to facilitate its mobility.
Main metallic elements made of stainless steel.
Diagram in the front panel with distribution of the elements similar to the real one.
- The unit includes:
- Stainless steel tunnel of 2000 x 550 x 550 mm approx. (78.74 x 21.65 x 21.65 inches
- approx.), which includes two transparent windows of 1000 x 130 mm approx. (39.37 x
5.11 inches approx.).
- Aerogenerator:
- Diameter: 510 mm. Starting air speed: 2.0 m/s.
- Maximum power output: 60 W. Voltage: 12 V. Maximum charging current: 5 A.
It includes a set of six blades. ATENG 11869 detail
The aerogenerator incidence angle can be modified to simulate different weather
conditions and it is possible to set different blade configurations (aerogenerator with six, three or two blades).
This unit allows to change the angle of every blade, as each one embeds its own calibrated protractor. The blades can be adjusted
in a 360° range.
Low friction alternator, which provides a smooth and silent output.
Friction less alternator and fixed shaft.
- Axial fan with variable speed for wind simulation:
- Maximum flow: 10650 mÂł/h. Maximum power: 1.5 kW.
It includes a finger guard.
- DC load regulator:
It regulates how power generated in the aerogenerator is distributed to and from the auxiliary battery and to the load. A display
- informs about the state of the charge, operating parameters and fault messages. The functions of the electronic protection are:
Overvoltage disconnection, short circuit protection of load and module, overvoltage protection at module input, over-temperature
and overload protection, and battery overvoltage shutdown.
- Auxiliary battery charger:
It carefully assesses the battery and then delivers the optimum charge required.
- Battery: Nominal voltage: 12 V. Nominal capacity (20 hours rate): 24 Ah.
- DC loads module:
Metallic box with diagram on the front panel.
- Two 12 V lamps.
- DC motor: Voltage: 24 V, power: 5 W.
Rheostat of 500 W.
Two manual switches.
- Independent connection for every load with the help of the four position load selector:
- Position 1: The aerogenerator or regulator operates at open circuit voltage.
- Position 2: The DC lamps and the rheostat are directly connected to the aerogenerator or regulator. These loads can be connected
independently or in parallel with the help of manual switches.
- Position 3: The DC motor is directly connected to the aerogenerator or regulator.
- Position 4: Bypass mode, there are no DC loads.
- Sensors/meters:
“J” type temperature sensor to measure the air temperature inside of the tunnel.
- The air speed is measured with an anemometer placed in the tunnel; anemometer range: 0.20 – 20 m/s.
Sensor measures the rotational speed of the aerogenerator (rpm).
DC voltage and current sensor. It is possible to know, in real time, the value of the DC voltage and the current given by aerogenerator,
measured before and after the regulator.
- Electronic console:
Metallic box.
Connector for the temperature sensor. Digital display for the temperature sensor.
Connector for the speed sensor. Digital display for the speed sensor.
Connector for the DC current and voltage sensor. Digital display for the current (DC) and Digital display for the voltage (DC).
Fan regulator for the axial fan. Switch for the axial fan.
Connectors for the force sensors. Digital displays for the force sensor.
Main switch.
Cables and accessories, for normal operation.
