A wind power station uses multiple wind turbines located together to produce electricity. It works by using blades to capture kinetic energy from wind and convert it to mechanical energy through a gearbox and generator, producing electrical energy. Modern turbines can generate between 0.5-2.5 megawatts of power annually, though their efficiency is typically around 30% of maximum theoretical capacity due to variable wind speeds. Wind power provides environmental and economic benefits but also has disadvantages like unreliable output, noise pollution, and impacts on wildlife. Future developments may improve flow modeling, remote sensing, and understanding of efficiency losses.

4. Wind Power Station
A wind power station is group of wind turbines in the
same location used to produce electric power
Wind energy source of renewable power which come
from air current flowing across the earth surface
Wind energy one of the fastest growing sources of new
electricity generation in the world to day

7. OPERATIONS
 Blades :
Blades “Catch” the wind and use it to rotate the low speed
shaft & convert kinetic energy to mechanical energy
 Gear box :
Gear box connect low- speed shaft to high-speed shaft
and increase speed “60 rpm-1800 rpm” and use it to
rotate Generator

8. Bearing : Bearing provide the smooth rotation
Generator : Generator convert mechanical energy to
electrical energy

9. Transformer (Step up) :
transformer develops the voltage from generator out put voltage
Tower : support the structure of the turbine
Controller : control speed of turbine

10. Efficiency
 A modern turbine has a maximum capacity of around
2000KW or 2MW
 A 2MW wind turbine will generate around 30% of
its maximum theoretical capacity resulting in 5256
MWh generated per turbine per year
Turbine can generate 0.5MW -2.5MW

11. Advantages of Wind Power
Environmental
Economic Development
Fuel Diversity & Conservation
Cost Stability

12. Environmental Benefits
No air pollution
No greenhouse gasses
Does not pollute water with mercury
No water needed for operations

13. Economic Development Benefits
Expanding Wind Power development brings jobs to
rural communities
Increased tax revenue
Purchase of goods & services

14. Fuel Diversity Benefits
Domestic energy source
Inexhaustible supply
Small, dispersed design

15. Disadvantages
Wind speed variable & unreliable
Kill Birds & Bats
Wind turbine produce large amount of noise pollution
Land use

16. Future of wind power station
The use of increasingly sophisticated flow
modeling techniques;
 Further validation of wake models;
The use of remote sensing techniques to
measure wind speed;
 Improved estimates of ‘loss factors’
 More sophisticated approaches to uncertainty
analysis.
