COMPONENTS OF A WINDMILL


2/15

BLADES - Most turbines have a minimum of two

blades. Standard windmills have more than twoblades.

ROTOR The portion of the wind turbine thatcollects energy from the wind. The rotor isattached to the generator shaft and holds theblades and hub.

PITCH - Pitch is the tilt of the windmill blades

also explained as the angle that the blades are atto capture the wind so the generator willrotate.

BRAKE - The brake is used to stop the windmill

in an emergency. LOW SPEED SHAFT - The low speed shaft is

effectively the drive shaft from the rotatingblades through to the gearbox.

GEAR BOX - It connects low speed shaft to thehigh speed shaft and increases the rotationalspeed.

GENERATOR - The generator is what convertsthe turning motion of a wind turbine's bladesinto electricity.

CONTROLLER - The controller starts up themachine at a specific wind speed.

ANEMOMETER - Measures the wind speed andtransmits wind speed data to the controller.

WIND VANE - Measures wind direction andcommunicates with the yaw drive to orient theturbine properly with respect to the wind.

NACELLE - The cover or caging that protects thegenerator and gearbox .

HIGHSPEED SHAFT - Drives the generator.

YAW DRIVE - the yaw drive is used to keep the

rotor facing into the wind as the wind directionchanges

YAW MOTOR - Powers the yaw drive.

TOWER - This is what holds the windmill up intothe airflow.

SUPPLY OF THE WIND POWER

The power is generated from the energy inthe wind, so a turbines power is determinedby its ability to capture that energy andconvert it to rotational torque that can turnthe generator and push electrons into thegrid. A taller tower provides access to

steadier winds, and larger blades capturemore wind energy. A larger generatorrequires larger blades and/or stronger winds.


12/15

Every wind turbine has a range of windspeeds, typically around 30 to 55 mph, inwhich it will produce at its rated, ormaximum, capacity. At slower wind speeds,the production falls off dramatically. If thewind speed decreases by half, power

production decreases by a factor of eight.

Operating Characteristics

Cut-in Speed

is the minimum wind speed at which the wind turbinewill generate usable power. This wind speed istypically between 7 and 10 mph.

Rated Speed is the minimum wind speed at which the wind turbine

will generate its designated rated power. Rated speedfor most machines is in the range of 25 to 35 mph.

Cut-out Speed At very high wind speeds, typically between 45 and 80mph, most wind turbines cease power generation andshut down.

Bangui Windmills

It provides 40% of the power requirementsofIlocos Norte

It produces electricity up to a maximum capacity

of 1.65MW, has a total of 33MW in all.

The expected life of the equipment is 21 years.

56,788tCO2e (tons of carbon dioxide equivalent)

of Greenhouse Gases will be reduced per year for

the duration of the project activity.

Electricity Generated

Assumed CF= 3o%

= (1.65 x 20)MW x 8760hrs x 0.3= 86,724MWh of electricity annually
