IT WILL BE VERY MUCH USEFUL FOR ELECTRICAL ENGINEERING STUDENTS

2. IJETEE (INTERNATIONALJOURNALOF EMERGING TRENDS IN
ELECRICALENGINEERING)
• It is international forum which tracks the latest
online research journal related to emerging
trends in electrical and electronics
engineering . Its headquarters is set in USA .
• It is an research forum for all students and
researchers faculties and academicians .

3. Emerging fields are :
• Renewable energy
• Power and communications
• Electric power generation
• Power quality and power electronics
• Electric traction
• Fuels and battery
• Electrical measurement
• Micro electric system
• High voltage engineering
• Turbine system and many more

4. Renewable Energy
• Renewable energy is the energy which is generated
from natural sources.
• i.e. sun, wind, rain, tides and can be generated again
and again as and when required.
• They are available in plenty and by far most the
cleanest sources of energy available on this planet. For
e.g. energy that we receive from the sun can be used to
generate electricity.
• Similarly, energy from wind, geothermal, biomass from
plants, tides can be used to fulfil our daily energy
demands.

5. Renewable energy sources
We know that 70% of energy comes from fossil
fuels .Growing dependency on fossil fuels will
cost us dearly and a lot. So there is need of
Renewable energy to compensate the energy
requirement of the developing countries
therefore there are some resources which is
required to explored and developed so that
cost of energy will be less .

7. Pros
Here are some of the pros and cons of using
renewable sources of energy:-
• The sun, wind, geothermal, ocean energy are available
in the abundant quantity and free to use.
• The non-renewable sources of energy that we are using
are limited and are bound to expire one day.
• Renewable sources have low carbon emissions,
therefore they are considered as green and environment
friendly.
• Renewable helps in stimulating the economy and
creating job opportunities. The money that is used to
build these plants can provide jobs to thousands to
millions of people.

8. • You don’t have to rely on any third country for
the supply of renewable sources as in case of
non-renewable sources.
• Renewable sources can cost less than
consuming the local electrical supply. In the
long run, the prices of electricity are expected
to soar since they are based on the prices of
crude oil, so renewable sources can cut your
electricity bills.
• Various tax incentives in the form of tax
waivers, credit deductions are available for
individuals and businesses who want to go
green.

9. cons
• It is not easy to set up a plant as the initial costs are
quite steep.
• Solar energy can be used during the day time and not
during night or rainy season.
• Geothermal energy which can be used to generate
electricity has side effects too. It can bring toxic
chemicals beneath the earth surface onto the top and
can create environmental changes.
• Hydroelectric provide pure form of energy but
building dams across the river which is quite
expensive can affect natural flow and affect wildlife.
• To use wind energy, you have to rely on strong winds
therefore you have to choose suitable site to operate
them.

10. Solar
energy
It is the most clean
form of energy in
world
Its supplies are
unlimited and
abundant.
Its installation is
once then no
recurring cost
Solar energy works
by converting the suns
rays into hot air for
heating

11. Wind energy
Wind power is growing at
a rate of 30% a year and is
harmless to the environment.
There are three minor
problems with wind energy
however, wind is not
available in sufficient
quantities in all locations all
of the time.
The current turbine
technology tends to be loud,
and birds can sometimes fly
into the propellers and get
killed.
Advancements in
technologies are helping to
solve or minimize these
issues.

12. Geothermal
energy
Geothermal energy is
power extracted stored under
the earth’s crust. This power
source from heat is generally
cost sustainable, and
generally environmentally
friendly.
Historically, effective,
usually reliable, mostly
geothermal energy extraction
has been limited to areas
near tectonic plate
boundaries.
Recent advances in
technology have significantly
widened the range of viable
resources, especially for
applications such as home
heating.

13. Biomass
energy
Biomass is biological
material from recently
living or currently living
organisms such as
trees and landfill
gasses and alcohol
fuels creating from
crops such as corn.
 Burning grease or
ethanol derived from
corn to run a vehicle
are two common
examples of biomass
energy production.

14. New Transmission Technologies
 High Voltage Overhead Transmission
-Voltage up to 1100 kV
-High EM radiation and noise
-High corona loss
-More ROW clearance
 Gas Insulated Cables/Transmission lines
 HVDC-Light
 Flexible AC Transmission Systems (FACTS)

15. Gas insulated Transmission Lines
 Benefits of GITL
- Low resistive losses (reduced by factor 4)
- Low capacitive losses and less charging
current
- No external electromagnetic fields
- No correction of phase angle is necessary
even for long distance transmission
- No cooling needed
- No danger of fire
- Short repair time
- Lower total life cycle costs.

16. Developments in Generation side
 Power reformer Energy System
 Distributed Generations
- Wind Power
- Fuel Cells
- Biomass etc.
 Combined Cycle Power Plants

17. Electricity Market is very risky
 Electricity is not storable in bulk quantity
 End user demand is typically constant
 Trading is directly related to the reliability of
the grid
 Demand and supply should be exact
 Electricity prices are directly related with
other volatile market participants
 Cost of continuity is more than cost of electric.

18. Power reformer Benefits
 Higher performance (availability, overload)
 Environmental improvement
 Lower weight
 Less total space requirement
 Lower cost for Civil Works
 Less maintenance
 Reduced losses
 Lower investment
 Lower LCC
