Nubenthan S. completed their industrial training at Wind Force (Pvt.) Ltd, a renewable energy company in Sri Lanka that operates wind farms. They learned about various aspects of wind turbine operation including the turbine components like blades, hub, and generator. They also studied wind measurement masts, the erection process for installing turbines, and safety plans. The training provided valuable practical experience in electrical engineering and renewable energy that will help with their future career.

3. INTRODUTION TO TRAINING
ESTABLISHMENT
• Wind Force (Pvt) Ltd is one of the Developing
Company in Sri Lanka.
• It was established in 2010 in North Western
Province(Puttalam).
• It has now a power plant in Pallai (Jaffna) and
was established in 2014.

4.  Joule and Beta (Pvt.) Limited Produces 12 MW per each.
(Joule 12 MW and Beta 12 MW)
 Wind Force is combined with REGEN Power Technologies.
 Wind Force mainly produces its services in field such as,
– Electrical Engineering
– Power & Renewable Energy

5. TRAINING EXPERIENCE
We had our 1st Industrial Training at several sites of the
company such as,
 Joule & Beta (Pvt.) Limited Head Office(Pallai).
 Karai Nagar Erection Project.
 Poonakari Wind Mast Project.

6. This training we studied mainly about Power Production and
Distribution facts related to those such as,
• Wind Turbines
• Wind Mast & Erection
• Escape and Rescue plan

7. WIND TURBINES
1. Blade
2. Hub
3. Pitch System
4. Tower
5. Generator
6. Nacelle
7. Yawing System

8. BLADE
The blades are used to extract the kinetic energy of wind and
convert to mechanical energy. Wind turbines can be designed
for 1 blade, 2 blades or 3 blades.

9. HUB
The hub holds the rotor blades together and transmits motion to generator
rotor.

10. PITCH SYSTEM
• Pitch control is the system which monitors and adjusts the
inclination angle of the blades and thus controls the
rotation speed of the blades. Initially the blades are at an
angle of 90° and it will pitch in towards 0° to start rotating.
• At higher wind speeds the blade pitch system reduces the
wind load on the blades and structure of the turbine by
pitching out the blades from 0 ° to maintain the rated rpm.

11. TOWER
• The tower of the wind turbine carries
the hub, nacelle and the generator.
Generally, it is an advantage to have a
high tower, since wind speeds increase
farther away from the ground.

12. GENERATOR
The Generator consists of Rotor & Stator and it converts mechanical
energy to electrical energy

13. NACELLE
 The nacelle holds all the components of the wind turbine,
including the electrical generator and the Hub.
 Service personnel may enter the nacelle from the tower of the
turbine.

14. Yawing System
The yaw system is the component responsible for the
orientation of the wind turbine rotor towards the wind.
There are 3 components in it.
• Yaw Bearings
• Yaw Drive
• Yaw brake

15. ADVANTAGES OF WIND ENERGY
• Wind energy does not emit any form of Air pollution.
• Wind turbines take up less space than the average power station.
• It’s a renewable source of energy where as other energy sources like
fossil fuels
– Are Depleting very fast
– Causes Air Pollution
– Causes Global warming
• Due to their nature, wind turbines can be placed in a variety of rather
inhospitable locations. In fact, they are ideal for mountainous/hilly
regions where regular power plants are unsuitable.

16. DISADVANTAGES OF THE WIND ENERGY
• The strength of the wind is not constant and it varies from zero
to storm force. This means that wind turbines do not produce
the same amount of electricity all the time. There will be times
when they produce no electricity at all.
• Many people feel that the countryside should be left
untouched, without these large structures being built.
• Wind turbines are noisy.

17. WIND MAST
• A measurement tower is a free standing tower or a
removed mast, which carries measuring instruments with
meteorological instruments such as thermometers and
wind velocity measurers.
• Measuring towers are an essential component of rocket
launching sites, since one must know exact wind
conditions for an execution of a rocket start.

18. ERECTION
• Installation of a system or machinery up to the point of
being able to start running is erection.
• There are 2 methods used in this erection process.
– Gin Poles
– Guided poles

19. GIN POLES GUIDED POLES

20. ESCAPE AND RESCUE PLAN
Escape Path

21. CONCLUSION
I’ve got a good opportunity to have my compulsory
session of Industrial Training in Wind Force (Pvt.)
Limited. During this valuable period I was able to take so
many practical experiences in Electrical Field and also
some kind of civil works. I can say I had a wonderful 3
months of time and hopefully this will help me lot in my
future.
