Wind power generation involves using wind turbines to harness the kinetic energy of wind and convert it into electrical power. Modern large wind farms have hundreds of individual wind turbines distributed over an area, with the turbines interconnected by a medium voltage grid. Key components of a wind turbine include the foundation, tower, nacelle, generator, rotor blades, and controls to orient the turbine and regulate blade pitch. While variable, wind power produces no greenhouse gases and can be cost competitive with fossil fuel plants.

POWER GENERATION

Wind Power

4. WIND POWER
1) Wind power is extracted from air flow using wind
turbines or sails to produce mechanical or electrical power. Wind
power as an alternative to fossil fuels. It is clean, produces
no greenhouse gas emissions during operation, and uses little land.
2) Wind farms consist of many individual wind turbines which are
connected to the electric network.
3) Wind is an inexpensive source of electricity, competitive with or in
many places cheaper than coal, gas or fossil fuel plants

5. WIND POWER
• Usually sites are pre-selected on the basis of a wind atlas, and validated with
on site wind measurements.
• Wind generators are practical where the average wind speed is 4.5 m/s or
greater.
• Since wind speed is not constant, the annual energy production of a wind
converter is dependent on the capacity factor.
• A well sited wind generator will have a capacity factor of about 35%. This
compares to typical capacity factors of 90% for nuclear plants, 70% for coal
plants, and 30% for thermal plants.

6. WIND POWER
• Wind power is very consistent from year to year but has significant
variation over shorter time scales.
• Wind energy production is growing rapidly and has reached around
4% of worldwide electricity usage.
• Wind energy is used to turn mechanical machinery to do physical
work, such as crushing grain or pumping water

8. WIND POWER
• The first windmill used for the production of electricity was built
in Scotland in July 1887 by Prof James Blyth of Anderson's College.
• Blyth's 10 m high, cloth-sailed wind turbine was installed in the
garden of his holiday cottage at Marykirk in Kincardineshire and
was used to charge accumulators developed by the
Frenchman Camille Alphonse Faure, to power the lighting in the
cottage, thus making it the first house in the world to have its
electricity supplied by wind power.

9. WIND POWER
• A larger and heavily engineered machine was designed and constructed in the winter
of 1887-1888 by Charles F. Brush.
• The Brush wind turbine had a rotor 17 m (56 foot) in diameter and was mounted on
an 18 m (60 foot) tower.
• Although large by today's standards, the machine was only rated at 12 kW.
• Wind power found new applications in lighting buildings remote from centrally-
generated power. Throughout the 20th century parallel paths developed small wind
stations suitable for farms or residences.

10. WIND POWER
• A wind farm is a group of wind turbines in the same location used
for production of electricity.
• A large wind farm may consist of several hundred individual wind
turbines distributed over an extended area, but the land between
the turbines may be used for agricultural or other purposes.
• In a wind farm, individual turbines are interconnected with a
medium voltage (often 34.5 kV).

13. WIND POWER
• Wind turbines are devices that convert the wind's kinetic energy into electrical power.
• The smallest turbines are used for applications such as battery charging for auxiliary
power.
• Arrays of large turbines, known as wind farms.
• In 1919 the German physicist Albert Betz showed that for a hypothetical ideal wind-
energy extraction machine, the fundamental laws of conservation of mass and energy
allowed no more than 16/27 (59.3%) of the kinetic energy of the wind to be captured.
This Betz limit can be approached in modern turbine designs, which may reach 70 to
80% of the theoretical Betz limit.

15. ENVIRONMENTAL EFFECTS
• Wind turbines have some of the lowest global warming potential per unit of electrical
energy generated.
• While a wind farm may cover a large area of land, many land uses such as agriculture
are compatible with it.
• There are reports of bird and bat mortality at wind turbines as there are around other
artificial structures.
• Wind turbines generate some noise. At a residential distance of 300 meters (980 ft.)
this may be around 45 dB, which is slightly louder than a refrigerator. At 1 mile
(1.6 km).
Wind Power

16. • Wind energy is the kinetic energy of air in motion, also called wind.
• Total wind energy flowing through with area A during the time t .
• Power is energy per unit time, so the wind power incident on A (e.g. equal to the rotor
area of a wind turbine).
• Wind power in an open air stream is thus proportional to the third power of the wind
speed; the available power increases eightfold when the wind speed doubles.
• Wind is the movement of air across the surface of the Earth.
• The global wind kinetic energy averaged approximately 1.50 MJ/m2 over the period
from 1979 to 2010, 1.31 MJ/m2 in the Northern Hemisphere with 1.70 MJ/m2 in the
Southern Hemisphere.
