IIT Jammu is a premier
institute of India with a vision to create tomorrow’s world through
technological interventions which are humanistic, creative and futuristic.
With this mission in
mind Department of Mechanical Engineering, IIT Jammu established a renewable
energy lab that includes Wind Energy Training System and ETC Characterisation
System.
Wind Energy Training System is a scaled down version of actual standalone Wind Turbine power plant. This system facilitates the students with working and configurable model of wind turbine. This system gives the insight about individual components and consequences of changing the operating points of any wind turbine defined in terms of wind speed and pitch angle. Students can learn concepts like I-V characteristic, cut-off, cut-in speed etc.
This system is developed such that it can work inside a closed laboratory with
an artificial wind generating unit, which makes it weather proof. User can
access and utilize the system capability at any time of the day without
worrying about the actual climatic conditions. This system uses a big fan
mounted on top of an Induction motor, the speed of which can be controlled by a
Variable Frequency Drive. User can control the speed of motor which further
controls the Wind speed using the Variable Frequency Drive. The variable wind
speed prompts Wind Turbine to convert Wind Energy into Electrical energy and
outputs three phase electrical output. The three-phase electrical output is
connected with a three-phase rectifier which converts electrical output from AC
to DC. The DC output is then further connected to a Charge controller and
Battery. A DC load can be connected at Charge controller output. The Battery is
further connected to a home inverter which provides clean useable AC
electricity.
Ecosense’s Wind Energy Training System enables students to learn about Wind Turbine technologies in easy and interactive manner. A user can study and understand about the following principles of Wind Energy Generation technology:
•
Evaluation of efficiency of charge controller
•
Evaluation of the cut-in speed of wind turbine experimentally
•
Evaluation of Tip Speed ratio (TSR) at different wind speeds
•
Evaluation of coefficient of performance of wind turbine
• Draw the
turbine Power versus wind speed curve
• Draw the
curve between TSR and coefficient of power
• Draw the
power curve of turbine with respect to the rotational speed of rotor at fix
wind speeds
•
Demonstrate the power analysis at turbine output
•
Demonstrate the power analysis at different branches of wind turbine energy
system with AC load only
•
Demonstrate the power analysis at different branches of wind turbine energy
system with DC load only.
An ETC characterization system for thermal analysis of fluids is a mini
closed loop ETC system to study the thermal characteristics of various fluids.
It uses an artificial sunlight so that it can be used inside a lab and is
independent of natural climate. A chiller is also connected to the system so
that once fluids get heated, students will be able to cool it down immediately
and study thermal characteristics of heating as well as cooling. This system
helps students in practical understanding of various technical parameters such
as efficiency and heat transfer at different flexible input parameters like
radiation, wind speed etc. The system has in built sensors which measure
parameters like pressure, temperature, flow rate etc., mounted on a control
unit. The equipment has the following features:
•
Artificial source of irradiation.
• Control
of irradiation level as per requirement
•
Artificial Source of Wind speed with provision to set wind speed as per
requirement
• Inbuilt
facility analogous to rooftop and hot water tank compatible to perform
experiment both outdoor and indoor environment.
• Water
heater available with storge tank for pre heating of water
• Chiller
tank available to quickly cool hot water
• Evaluate
system efficiency and heat transfer
• An active
measurement panel to measure inlet temperature, pressure etc.
• Inbuilt
facility analogous to rooftop and hot water tank compatible to perform
experiment both outdoor and indoor environment.
•
Artificial Source of Wind speed with provision to set wind speed as per
requirement.
