Computer Controlled Wind Energy Unit (EEEC)
PL-263405
The "EEEC" Computer Controlled Wind Energy Unit is a laboratory-scale system that facilitates the study of kinetic wind energy conversion into electrical power and allows examination of various factors affecting this generation process. It features a stainless steel tunnel, an aerogenerator, and an axial fan with variable speed control, which is computer-operated. The main elements of the aerogenerator include a rotor, capable of holding multiple blades, and a generator that forms the core of the energy conversion system. The unit's fan speed can be adjusted, allowing the airflow to rotate the aerogenerator’s rotor, which in turn drives the generator to convert this kinetic energy into electricity.
With adjustable settings, the aerogenerator allows modification of the incidence angle and blade angle. The blades are removable, providing flexibility in blade configurations, which makes it possible to analyze their effects on energy efficiency and power output. The unit includes a DC load regulation system with an auxiliary battery charger, battery, and DC loads module, comprising lamps, rheostat, motor, load selector, and switches for various load selections. Sensors within the unit provide real-time measurement of critical parameters, including air temperature, airflow speed, rotor speed (rpm), voltage, and current. A temperature sensor before the rotor and an airflow sensor in the tunnel contribute to a comprehensive analysis of both environmental and performance variables. Additionally, voltage and current sensors measure power output, both before and after regulation, enabling precise assessments of efficiency and power.
Furthermore, the unit can determine the thrust force applied to the wind turbine in the direction of the wind and measure the mechanical torque during turbine operation. The EEEC unit is equipped with the EDIBON SCADA system, which includes the main unit, a Control Interface Box, Data Acquisition Board, and specialized software for process control, data acquisition, and monitoring of all operational parameters, supporting in-depth exploration and analysis of wind energy applications.
