Wind Energy Trainer (Model : XPO-WET)

This table-top wind tunnel is an advanced educational tool designed for in-depth exploration of wind energy concepts. Featuring transparent side and top covers with a protective cage, students can easily identify the components of a windmill. The system incorporates a 3-phase motor with axial fan blades serving as a blower to simulate variable wind conditions. A Variable Frequency Drive (VFD) provides precise control over the motor/blower speed, allowing for a continuously variable wind speed setting. The curriculum supported by the system covers renewable energy basics, energy conservation, charge controllers, storage systems, and inverters.

SALIENT FEATURES:

  • Table top wind tunnel with side/ top covers having transparent viewing window & protection cage to facilitate identification of components of windmill.
  • 3 phase motor with axial fan blades as blower to simulate variable wind.
  • VFD to control speed of motor/ blower with continuously variable speed to set wind speed.
  • Renewable energy basics, energy conservation, charge controller, storage system & invertor etc.
  • Converting kinetic wind energy into electrical energy in laboratory using BLDC generator.
  • 500mm cuboid using aluminium profile, 2 such racks connected each other to form wind tunnel containing wind blower and wind turbine.
  • Pitching and yawing provision provided. Wind turbine mounted on Pillar with bearing to facilitate yawing.
  • Optional PC interface.
