Wind turbine simulator - Network injection

EOLYP is a test bench dealing with the study of the hyper synchronous activity of a wind turbine for its electricity production aspects, excluding the mechanical aspects. Due to noise pollution and draughts, which are incompatible with a classroom environment, the propeller has been replaced by a variable speed drive motor.

Educational objectives
• Understanding the mechanical & electrical principles of a wind turbine.
• Studying the hypo-synchronous and hyper-synchronous operating modes of an asynchronous motor.
• Studying the synchronization of the electrical network.
• Calculating the efficiency of the energy production system.
• Using a clamp-on Ammeter.
