Parts of Wind Turbine
Hubs

• The hub holds the rotor together and transmits
  motion to nacelle
• The important aspects
• Blades are attached to the hub.
• Hub is attached to the main
• shaft.
• Hub contains pitching
• mechanism.
• Fixed or Variable Pitch.

9
Rotor
Collects energy from the wind, consists of two
or more wooden, fiberglass or metal blades which
rotate about an axis. Axis can be horizontal
or vertical Rate determined by the wind speed
and the shape of the blades. The blades are
attached to the hub
10
Towers
Monopole (Nearly all large turbines) Tubular
Steel or Concrete Lattice (many Medium
turbines) 20 ft. sections Guyed And Tilt-up
monopole

• It not just a support structure but also for
  raising WTG, keeps blades clear from ground can
  reach stronger winds at higher elevations.

11
Blades

• Number of blades that make up a rotor and the
  total area they cover affect wind turbine
  performance.
• The wind must flow smoothly over the tip of the
  blade for smooth functioning.
• Spacing between the blades
• should be enough to avoid
• turbulence, most of the
• wind turbines have 2 or 3
  blades.

12
Coupling

• The coupling is placed between the gearbox and
  the generator.
• Coupling should be understood as flexibility
  that allows for some slight differences in
  alignment between the generator and the gearbox.
• Because during running operation,
• both gearbox and generator can have tendencies
  for slight movement in relation to each other.

• Two coupling are there
• One is Arpex and one Fluid coupling

13

Shaft

• Main Shaft is hollow cone
• type
• Shaft connects Rotor, Hub and Gear box
• Main Bearing is fitted on
• the main shaft.
• Gearbox is placed at other end of shaft.

14
Gear-Box

• The gearbox in a wind turbine does not "change
  gears". It normally has a single gear ratio
• It between the rotation of the rotor and the
  generator.
• For a 600 or 750 kW machine, the gear ratio is
  typically approximately 1 to 50

15
Use a Gearbox ?
One of the most important main components in the
wind turbine is the gearbox. Placed between the
main shaft and the generator,. Its task is to
increase the slow rotational speed of the
rotor blades to the generator rotation speed of
1000 or 1500 revolutions per minute (rpm).
16
Generator

• The generator is the unit of the wind
• turbine that transforms mechanical
• energy into electrical energy.
• The blades transfer the kinetic energy from the
  wind into rotational energy in the transmission
  system, and the generator is the next step in the
  supply of energy from
• the wind turbine to the electrical grid.

• Asynchronous type
• Produces A/C output 50 Hz.
• Two speed ( Four and six Pole)

17
Yaw Control (Yawing Facing the Wind)

• To keep the swept area perpendicular to the
  predominant wind direction
• Yaw Fixed
• Yaw Active
• Tail Vane
• Yaw ErrorThe wind turbine is said to have a yaw
  error, if the rotor is not perpendicular to the
  wind. A yaw error implies that a lower share of
  the energy in the wind will be running through
  the rotor area

Mechanism of Generating Power from Wind
21
Wind Turbine Generator
Types of Wtg used
Conventional WTG with Gear Box
Direct Drive Generator

• Gear box is used between the rotor and generator
  mechanism to increase speed.
• Maintenance is high Low weight and cost.
• Asynchronous generator (Induction motor) is used.

• Do not have a speed-increasing gearbox between
  rotor and generator.
• Reduced maintenance and increased efficiency.
• Increased weight and cost.
• Permanent magnets on the generator rotor, and
  wound stator elements.

Operating Characteristics

• Cut in Speed The minimum wind speed at which
  the wind turbine will generate usable power.
• Rated Speed The minimum wind speed at which
  the wind turbine will generate its designated
  rated power.
• At wind speeds between cut-in and rated, the
  power output from a wind turbine increases as the
  wind increases.
• Cut out Speed The wind speed at which shut
  down occurs is called the cut-out speed.
• At very high wind speeds, most wind turbines
  cease power generation and shut down.
• Cut-out speed is a safety feature which protects
  the wind turbine from damage.

Rated wind speed 14m/s
Cut out wind speed 25m/s
