Parts of a Wind Turbine Kinds of Wind Turbine Energy in the wind

Introduction

General parts or a wind turbine:

TowerRotorNacelle

Awind turbine is a device that converts kinetic energy from the wind intomechanical energy. If the mechanical energy is used to produce electricity,the device may be called awind generator

Parts of a Wind Turbine

Kinds of Wind Turbine Energy in the wind

Introduction

Big wind turbines

Mwatts order

Actual generation : 1-2 Mw

Next Generation: 5Mw

In order to produce energy as an industry

Flying wind turbines will have this use

because of the big amount of energy in

high altitude.


5/20



Introduction

Small wind turbines

Kwatts order

From 0,2 to 15 Kw

Home use and specially for

difficult access places

Flying wind turbines will not have economical sense


6/20



Introduction

Horizontal axis: Vertical axis:

Darrieus Savonius

Both kind of axis will be used as flying wind turbines, it will depend onthe technology we use


7/20



There are 3 factors: Air density:

Relation between density, mass and kinetic energy

Rotor area:

Relation between rotor area, and rotor diameter

Wind speed

This is going to make us choose the kind of wind turbine


8/20



We have to compare the wind area that are crossing theblades in every moment...otherwise we could


9/20

Betzs law Wind Atlas Mathematical calculations

Theory

To convert Kinetic energy in mechanical energy (and then toelectricity)How?

Compare V1, V2, P y Po

Conclusion:16/27--------59%

Problems

Betzs law

Wind Atlas Mathematical calculations

Theory

It represent Speed, Frequency andthe relation between them.

How to measure when the

turbine is moving all the time?

How to control de direction ofthe flying wind turbine?

How flat is the surface:The flatter the better


11/20

Betzs law

Wind Atlas Mathematical calculations

Theory

Good measurement in the position withthe rotor will be, will give us a good ideaon the quantity of energy that we canobtain.

The measurements for Flying windturbines are for huge areas.

Energy loses

Betzs law Wind Atlas

Mathematical calculationsTheory

Weibull Distribution:In probability theory and statistics, theWeibull

distribution is a continuous probability distribution.Important: Probability

Define wind variation)(this is important because of thedesign and cost)

what is the value of the area under the line?

Same problem: difficult tomeasure

Search and selection of the work area Project executionDesign

Meteorological modelling enterprises: Mesoscale analysisWind Virtual data about:

- Altitude wanted

- Location (the best ones)

Preliminar y selection of locations: Energy transport possibilityAccesibility and facility about how to build the wind farmEtc.

Evaluation of the wind power(huge importance)Measurement towersWeibull DistributionWind turbine selectionMicrositing

Description

Electric installations (calculation)

Environmental Impact Study process

Noise, environment impact, destruction of the terrain and animal impact

Animal Impact (birds) : 3 kinds (bigger than with the other kind of wind turbines).

Documentation process(5 steps) : knowledge, Information, evaluation, outside workplanning, outside work .

BACI analysis

Search and selection of the work area

Placement of the wind turbines

Testing period Maintenance

Execution ofworks

Test of every element thatwe have in the wind farm

Compare data (wind realcalculation, wind study calculation)

Compare production (study data)

Testing Period

Every Flying wind Turbine General test of all Wind Farm

Problems test:- Frequency- Production loses- Etc.

Execution ofworks

Advantage:Its not a new technology,it is used especially for

offshore wind farms

Disadvantage:Flying wind turbines are

moving continuously,that means hugedifficulties for themaintenance team.

CONCLUSION

Advantages PresentedAt higher altitudes, wind has more power and velocity and is moreconsistently predictable. As power generated goes up because of higher

wind resistance proportional to the cube of relative velocity, morepower can be generated. That works out to be some 8 27 times the

power produced at ground level. The tethers can haul in thekites/balloons housing the turbines during storms or for generalmaintenance work. Less pollution is an advantage, as well as the factthat it will not take up much precious ground space for installation.

Not in every document found this idea go in the same way, some of thewriters have the opposite point of view.

Small improvements mean benefits
