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

Elements of power station

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

Advantages of Wind Power

Environmental

Economic Development

Fuel Diversity & Conservation

Cost Stability

Environmental Benefits

No air pollution

No greenhouse gasses

Does not pollute water with mercury

No water needed for operations

Economic Development Benefits

Expanding Wind Power development brings jobs to

rural communities

Increased tax revenue

Purchase of goods & services

Fuel Diversity Benefits

Domestic energy source

Inexhaustible supply

Small, dispersed design

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.
