4. PARTS OF A WIND TURBINE

5. WIND TOWER
LATTICE
TOWER
• Steel Bars
• Less Material
• Cheap, light
weight
• Lighter
foundation
• More
maintenance

6. WIND TOWER
TUBULAR
TOWER
• Tubular
sections
• 10m to 20m
• Good
mechanical
strength
• Good looking
• No chance of

7. WIND TOWER
GUYED TOWER
• Partial support
by tower and
guy wire
• 4 wires at 45O

8. WIND TOWER
HYBRID TOWER
• Combination of truss, tubular and guyed
tower.
• Truss portion  lighter foundation
• Guyed portion  reduces size of tubular
section
• Tubular portion  Good mechanical
strength, good looks and less
maintenance.
• Easy transportation

9. BRAKING SYSTEM
MECHANICAL BRAKING ( SECONDARY BRAKING)
DISC BRAKES
AERODYNAMIC BRAKING ( PRIMARY BRAKING )
ACTIVE PITCH CONTROL BRAKING
BRAKING BY PITCHING BLADE TIPS

10. TYPES OF ROTOR
HORIZONTAL AXIS
Single Blade : Less Drag Force, Material Saving
Two Blade : Less Drag Force, Improved Visual
Appearance
Three Blade : Stable And Uniform Aerodynamic
Loading
Multi Blade : High Torque Application And Easy
Start.

11. TYPES OF ROTOR
VERTICAL AXIS
DARRIEUS
Generator and Gear box are mounted at ground
Simple tower construction and economical
Less efficiency and less mechanical strength (Guy
Wire Support)

12. TYPES OF ROTOR
VERTICAL AXIS
SAVONIUS
Less efficiency
High Torque
Less speed

13. TYPES OF ROTOR
VERTICAL AXIS
MUSGROVE
ROTOR
