4. Course Certificate

5. Learning objectives
After completing this course, I will be able to:-
 Apply basic engineering models for wind speed and determine the annual energy production for a wind turbine.
 Analyse measured wind data and determine the mean wind speed and turbulence.
 Perform simple calculations for assessing wind farm projects and for calculating the cost of energy from wind.
 Account for the configuration and energy production of different wind turbine designs.
 Carry out calculations of thrust and power for a wind turbine.
 Calculate the mass of a turbine blade based on different material’s properties.
 Define boundary conditions and loads on beams and calculate reactions and internal forces.
 Apply a strategy for controlling the rotor speed of a variable speed wind turbine.

6. Introduction to wind energy
The production of energy with the help of wind. It is most simple sustainable, renewable energy source .
. Need for
wind energy:
 Power Generation
 Economic development
 It’s sustainable, renewable
energy source
 Environment friendly
 Cheaper & easy to access
Professor Niels-Erik Clausen, delivering the Lecture through online mode

7. .
 Wind energy is the converting of
wind power to electrical power
through the use of windmills or
turbines .
 Electricity produced is sent to
transformers where voltage is
increased and sent to the power grid
via transmission lines.
What is Wind Energy?

8. .
 The power in wind is proportional to the
cubic wind speed(v³).
WHY?
 Kinetic energy of an air mass
isproportional to v²
 Amount of air mass moving past a given
point is proportional to wind velocity (v)
POWER OF WIND

9. .  A typical 600 kW turbine costs about $450,000.
 Installation costs are typically $125,000.
 Therefore, the total costs will be about $575,000.
 The average price for large, modern wind farms is
around $1.000 per kilowatt electrical power
installed .
 Modern wind turbines are designed to work for
some 120,000 hours of operation throughout their
design lifetime of 20 years. (13.7 years non-stop)
 Maintenance costs are about 1.5-2.0 percent of the
original cost per year.
COST CALCULATIONS

10. .
 Wind is free, wind farms need no fuel.
 Produces no waste or greenhouse
gases.
 The land beneath can usually still be
used for farming.
 Wind farms can be tourist attractions
 Advantages  Disadvantages
The wind is not always predictable some days have no wind.
Suitable areas for wind farms are often near the coast, where land is
expensive.
Some people feel that covering the landscape with these towers is
unsightly.
Can kill birds-migrating flocks tend to like strong winds. However,
this is rare, and we tend not to build wind farms on migratory
routes anyway.
Can affect television reception if you live nearby.
Can be noisy, Wind generators have a reputation for making a
constant, low, "swooshing" noise day and night, which can drive you
nuts.

11. .
 Declining Wind Costs
 Fuel Price Uncertainty
 Federal and State Policies
 Economic Development
 Green Power
 Energy Security
Drivers for Wind Power

12.  Livelihood affect
 Environmental impact
 Financial problem
 Does the community have an option to
invest as a shareholder?
