A wind turbine obtains its power input by converting the force of the wind into a torque acting on the rotor blades

The amount of energy which the wind transfers to the rotor depends

- on the density of the air- the rotor area- and the wind speed.

In other words you can get more energy:

- the "heavier" the air- the “bigger” the rotor- the “higher” the wind speed

How does it work

12 Steps to install a wind farm

1. WIND ASSESSMENT... available wind data will be used to estimate how much

energy the wind farm will produce.

2. WIND FARM DESIGNWind data combined with topographical information to design

the wind farm..... to model wind flow, ... turbine performance... sound levels ... to optimize the location of WTG ... design the access roads... turbine foundations ... local electric network... grid connection

15

3. ENVIRONMENTAL STUDY... to identify any impacts on landscape, plants and wildlife,

soil and water, land use, aviation, telecommunications, etc.

4. LAND ACQUISITION... to negotiate “option” agreements to use land

5. PERMITTING AND PUBLIC CONSULTATION... seek municipal, provincial and federal permits before the

project can go ahead. ... meet the local communities to present the project, solicit

their feedback and seek community support.


16

6. ECONOMIC AND FINANCIAL ANALYSIS… demonstration of the economic viability of the project to raise

the funds… estimate the cost of turbines and their installation, as well as

roads, electrical system, operation and maintenance, etc.... estimate the income by using the energy production of the

wind farm over the lifetime of the project

7. MANUFACTURINGWTG parts are manufactured and pre-assembled into the main

components at the factory and shipped to the wind farm site where the final assembly will take place.


17

8. SITE PREPARATIONThe wind farm site will be prepared before the WTG will arrive to

site. ... access roads, clear the areas where turbines will be erected... preparation of the foundations (do the excavating; installing

the formworks; pouring concrete)

9. CONSTRUCTIONAfter arrival of all components, the assembly can take place by

using a crane to erect the tower and install the nacelle and rotor with its hub and blades. Same time the electrical works will be performed


18

10. COMMISSIONINGThe wind farm will tested before becoming fully operational.

11. OPERATION AND MAINTENANCEA variety of skill sets are required to ensure the effective operation of a Wind Farm (activities be performed on a regular basis throughout the project’s, monitoring and analyzing performance, performing preventive maintenance and repairs on the turbines)

Selection Criteria for Wind Turbines

23

Different size of WTGs / Cost per kW

WTG: 1MW, 70m hub

WTG: 2MW, 100m hub

24

Large wind farm vs. smal wind farm

Availability of 400t cranes is higher than 600t

WTG <2MW should be selected for Pakistan
