A wind power station uses multiple wind turbines located together to produce electricity. It works by using the blades to capture kinetic energy from wind and convert it to mechanical energy by spinning a shaft, which is then converted to electrical energy by a generator. Key components include blades, a gearbox, generator, transformer, tower, and controller. Modern turbines can generate between 0.5-2.5 megawatts of power, with efficiencies around 30% of maximum theoretical capacity. Wind power provides environmental and economic benefits but also has disadvantages such as variable wind speeds and potential impacts on wildlife. Future developments include more accurate wind modeling and remote sensing techniques.

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
