Wind Turbine


The wind turns the blades connected to rotor shaft inside the nacelle. The rotation of the shaft then goes into a gearbox which increases the rotation speed. The generator converts the rotational kinetic energy into electrical energy.

The wind generator system can be on-grid (grid connected) or off-grid (standalone) system.

Technical Data:

  • Horizonl Axis Wind Turbine (HAWT)
  • Vertical Axis Wind Turbine (VAWT)
  • Off-grid/Standalone system
  • On-grid/Grid connected system
  • Small and Mid-size wind turbine

The wind generator system consists of:

  • Nacelle – the housing of the generator, gearbox, breaks and drive train.
  • Tower/Pole – structure that support the nacelle and it can be tilt-ups, guyed lattice, and freestanding. Height of pole is necessary to provide safe condition and important factor in the design and wind speed
  • Inverter – device that convert current from direct current DC to household conventional alternative current AC in off-grid system or connect to grid for grid connected system
  • A dump load – device to divert excess generated energy in off-grid system
  • Battery bank – energy storage for the generated energy in off-grid system
  • Controller – system controller for the operation, performance and safety
