Computer Controlled Wind Energy Unit

The Computer Controlled Wind Energy Unit, contains an aerogenerator, in laboratory-scale, and is used to study the conversion of kinetic wind energy into electrical energy and to study the influence of some factors on this generation.

ATENG 11867 — Computer Controlled Wind Energy Unit

(for main items)

• With this unit there are several options and possibilities:
• Main items: 1, 2, 3, 4, 5 and 6.
• Optional items: 7, 8, 9, 10 and 11.
• Let us describe first the main items (1 to 6):
• 1 ATENG 11867. 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.
  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.
  Computer controlled axial fan with variable speed for
• wind simulation:
• Maximum flow: 10650 m³/h. Maximum power:
• 1.5 kW. It includes a finger guard.
• Unit: ATENG 11867
• 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 in 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, depending on the selection made in the computer. 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:
  “J” type temperature sensor to measure the air temperature inside of the tunnel.
• The air speed is measured with a sensor placed in the tunnel; sensor range: 0.20 – 10 m/s.
  Optical 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.
• Force sensor to measure the mechanical torque of the wind turbine, range: 0 – 600 g.
• Force sensor to measure the thrust force on the wind turbine, range: 0 – 3000 g.
• The complete unit includes as well:
  Advanced Real-Time SCADA.
  Open Control + Multicontrol + Real-Time Control.
  Specialized Control Software based on LabVIEW.
  National Instruments Data Acquisition board (250 KS/s, kilo samples per second).
  Calibration exercises, which are included, teach the user how to calibrate a sensor and the
  importance of checking the accuracy of the sensors before taking measurements.
  Projector and/or electronic whiteboard compatibility allows the unit to be explained and
  demonstrated to an entire class at one time.
  Capable of doing applied research, real industrial simulation, training courses, etc.
  Remote operation and control by the user and remote control for technical support,
  are always included.
  Totally safe, utilizing 4 safety systems (Mechanical, Electrical, Electronic & Software).
  Designed and manufactured under several quality standards.
  Optional ICAI software to create, edit and carry out practical exercises, tests, exams,
  calculations, etc. Apart from monitoring user's knowledge and progress reached.
  This unit has been designed for future expansion and integration. A common expansion is
  the Scada-Net (ESN) System which enables multiple students to simultaneously
  operate many units in a network.
