EN 04.2 – Grid Connected Windmill Energy Plant Trainer

With the equipment EN 04.2, we emulate the behaviour of a wind turbine in a practical and educational way. An electric motor operates as the turbine on a windmill moving a three-phase synchronous permanent magnet generator, which converts the transmitted mechanical energy to electric energy.


The generated electricity is alternating current three-phase, having to be transformed into direct current to feed the inverter, which transforms it into alternating current at an appropriate frequency, and other necessary features to connect to the network.

The equipment is designed for a very visual and intuitive operation, quickly understand the functioning of the whole system, not just knowing the elements that compose the unit, but also having to connect them through the supplied cables for this purpose. This is achieved by the provision of equipment in modular panels. It also has a computer from which to control the operation of the equipment and get all the necessary variables for system analysis.

Learning Objectives
  • Study of the operation and components of a wind generation system connected to the mains.
  • Plotting of the characteristic curves of the generator:
    • Three phase voltage according to the rotation speed.
