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

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

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

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

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

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

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.
