This presentation will describe the basics of wind power generation the technologies used in wind power. the energy conversion process used in wind power system are explained. This material was prepared for Debre Brihan Univesity 4th year power engineering students of 2017.
Betz's law indicates the maximum power that can be extracted from the wind, independent of the design of a wind turbine in open flow. It was published in 1919, by the German physicist Albert Betz.[1] The law is derived from the principles of conservation of mass and momentum of the air stream flowing through an idealized "actuator disk" that extracts energy from the wind stream. According to Betz's law, no turbine can capture more than 16/27 (59.3%) of the kinetic energy in wind. The factor 16/27 (0.593) is known as Betz's coefficient. Practical utility-scale wind turbines achieve at peak 75% to 80% of the Betz limit.[2][3]
The Betz limit is based on an open disk actuator. If a diffuser is used to collect additional wind flow and direct it through the turbine, more energy can be extracted, but the limit still applies to the cross-section of the entire structure.A wind turbine is a device that converts kinetic energy from the wind into electrical power. The term appears to have migrated from parallel hydroelectric technology (rotary propeller). The technical description for this type of machine is an aerofoil-powered generator.
The result of over a millennium of windmill development and modern engineering, today's wind turbines are manufactured in a wide range of vertical and horizontal axis types. The smallest turbines are used for applications such as battery charging for auxiliary power for boats or caravans or to power traffic warning signs. Slightly larger turbines can be used for making contributions to a domestic power supply while selling unused power back to the utility supplier via the electrical grid. Arrays of large turbines, known as wind farms, are becoming an increasingly important source of renewable energy and are used by many countries as part of a strategy to reduce their reliance on fossil fuels.
Wind is a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun, the irregularities of the earth's surface, and rotation of the earth. Wind flow patterns are modified by the earth's terrain, bodies of water, and vegetation. Humans use this wind flow, or motion energy, for many purposes: sailing, flying a kite, and even generating electricity.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

2. Wind Energy
When wind strikes an object, it exerts a force in an attempt to
move it out of the way. Some of the winds’ energy is
transferred to the object, in this case the windmill, causing it
to move.
Wind Today!!!
Windmills are used for pumping
water from deep underground.
Modern wind turbine is the result of
design and material advances made
during the 1980s and 1990s, which
enabled wind turbines to become
increasingly efficient.
Today, wind turbines are size same
as the traditional European windmill.
It can generate 250 to 300 kilowatts of
power- a nearly tenfold increase in
efficiency.
History of Wind usage:
one of the earliest energy resources.
Recorded in history, first to power boats
and grind grain, later to pump water, press
oil, saw lumber and make paper.
Windmills were mentioned at the
beginning of Islamic civilization (7th century).
Windmills were developed in Persia and
used paddles made of bundled reeds.
Egyptians may have been the first to go up
the Nile river around 4th century B.C,
powered by wind.
Ancient Chinese used vertical axis
windmills to grind grain and pump water.
Windmills were introduced to Europe by
the crusaders around 1300 A.D
*windmills used for pumping water.
3. Wind turbines convert the kinetic energy in the
wind into mechanical power.
This mechanical power can be used for specific
tasks (such as grinding grain or pumping water)
or a generator can convert this mechanical
power into electricity.
A wind turbine works the opposite of a fan.
Instead of using electricity to make wind, like a
fan, wind turbines use wind to make electricity.
Thewind turns the blades, which spin a shaft, which
connects to a generator and makes electricity.
4. • The energy in the wind turns two or three propeller-like
blades around a rotor. The rotor is connected to the main
shaft, which spins a generator to create electricity.
• Wind turbines are mounted on a tower to capture the
most energy. At 100 feet (30 meters) or more above
ground, they can take advantage of faster and less
turbulent wind.
5.
6. Wind turbines operate on a simple principle:
• The energy in the wind turns the propeller-like blades
around a rotor.
• The pitch of the blades makes optimum use of the
wind direction.
• The rotor is connected to the main drive shaft, which
spins a generator to create electricity.
• Wind turbines are mounted on a tower to capture the
most energy at 30 meters or more above ground, they
can take advantage of faster and less turbulent wind.
• Wind turbines can be used to produce electricity for a
single home or building, or they can be connected to
an electricity grid for more widespread electricity
distribution.

9. Description
2. Is the rotor. The rotor provides the
blades to rotate.
4. This is brake. It’s very important to
have a brake in a wind turbine, if
something is wrong or it is going to
fast. Then it will brake and stop the
wind turbine.
5. is a low-speed shaft, it
goes into a big cog wheel and this goes
into a smaller cog wheel. The small
cog wheel rotates faster than the big
cog wheel.
7. This is the generator. It’s almost
like a generator in a car.
13. It’s a yaw draw, it makes the wind
turbine rotate in the wind direction.
15. Is the tower. The entrance is
placed in the bottom of the tower
11. Advantages of Wind Power
• Environmental Benefits
• Economic Development Benefits
• Fuel Diversity & Conservation Benefits
• Cost Stability Benefits
• No pollution.
• Lowest prices renewable resources
• Don’t produce atmospheric emissions that cause
acid rains and green house effects.
12. Disadvantages
• Birds - A Serious Obstacle
• Noise Disturbances
• Cost of Wind Turbine
• Threat to Wildlife
• Wind Can Never Be Predicted
• Suited To Particular Region Visual Impact
• Wind energy cannot be stored (unless batteries are
• used)
• Good wind sites are often located in remote locations
• Wind resource development may compete with other
uses for the land and those alternative uses may be
more highly valued than electricity generation.
13. Site Selection
Technical Factors affecting site selection:
• High Average annual wind speed
• Low Cost of Construction
• Close Distance from Utility line or customers
• Prevailing wind Direction
• Surface Roughness
14. Source-wise Share of Renewable Energy Capacity
(March, 2013)
Total Installed capacity of wind energy in India
19051.46 MW
15. Wind Power
= 1/2 x air density x swept rotor area x (wind speed)3
= (KW)
Jaisalmer wind farm
[The 2 largest off shore wind farm in the world
16. • Wind turbines are
noisy
• Each one can generate
the same level of noise
as a family car
travelling 70 mph
• Some people thinks
that the large towers of
wind turbines destroys
the view of the
landscape
Onshore disadvantagesOnshore advantages
• A regular onshore turbine
last for around 20 years
• Normally it takes about 2-3
months before the wind
turbine has paid itself back.
• This also includes the
energy, which were used to
produce, install, maintain
and remove the wind
turbine.
• Cheaper foundation
• Cheaper integration with
electrical-grid network
17. Offshore Advantages
• A offshore wind turbine is
stronger than a onshore
turbine. It lasts around 25-
30 years, and produces
about 50 % more energy
than a onshore turbine.
• When a strong wind blows,
it produces around 3-5 MW
per hour.
• Higher and more constant
wind speed
Offshore Disadvantages
• More expensive to built
• More difficult to
maintain and access
