Wind Energy Training System is a compact scaled down version of an actual Wind Turbine standalone power plant. The system enables user to study wiring and interconnections of different components involved in the system to develop basic understanding of working and operation of a Standalone Wind Turbine system. Through the help of experiments a student can understand underlying principles of Wind Turbine, its applications in standalone system by doing various experiments. The system also provides scope for further research.

Wind Energy Training system is an indoor system which utilises a fan to act as artificial wind source. The fan is connected with an induction motor whose speed can be controlled via a variable frequency drive. As the wind speed can be controlled the generation from wind turbine can also be controlled which makes this system to be used indoors. The Wind turbine generates a three phase AC power which is further connected to a rectifier and a charge controller. The DC output from charge controller can be used by DC Loads and Inverter.

Using this experimentation system, users can study and understand concepts like cut-in, cut-off and rated speed, coefficient of power, tip speed ratio, pitch angle, correlation between coefficient of power and tip speed ratio etc.
