3. INTRODUCTION
 Ever increasing demand has led us to switch unto
non renewable source of energy. Recent study
revealed that within next few decades renewable
sources which accounts 80 percent of worlds total
energy production is about to finish.
 With the advancement of technology number of
methods are available to concentrate the solar
power. This technology is known as concentrated
solar power

4. CONCENTRATED SOLAR
POWER• Require Direct Sunlight
– Concentrating solar power
systems cannot
reflect diffuse sunlight,
making them ineffective
in cloudy conditions
• Two Approaches
– Power Tower
– Parabolic Trough
DIRECT NORMAL SOLAR RESOURCE IN THE SOUTH WEST

5. SOLAR ELECTRIC
GENERATING SYSTEM
• SOLAR FIELD COMPONENS
• HEAT COLLECTION ELEMENTS
• MIRRORSFLEXHOSES
• MIRROR WASHING & REFLECTIVITY
MONITORING
• MAINTENANCE TRACKING
• COLEECTOR ALIGNMENT
• PROJECT START-UP SUPPORT
• THERMAL CYCLING & DAILY STARTUP

6. SOLAR FIELD COMPONENTS
A simple problem with a single components,such as an
HCE,can effect many thousands of components in a
large solar field.
Three components in particular are worthy of discussion
because they have represented the largest problems.
Such as:- HCEs
MIRRORS
FLEXHOLES

7. HEAT COLLECTION
ELEMENTS(HCEs)
• A number of HCE failure mechanism have been identifiedt
the SEGS plants.
• Loss of vaccum,breakage of the glass
envelope,deterioration
of the selective surface & bowing of the stainless steel tube
have been the primary HCE failures all of affect which thermal
efficiency.
• Future HCE designs should
Use new tube materials to minimize bowing problems
Allow broken glass to be replaced inside in the field
Continue to improve theselective coating,emittance

8. MIRRORS
• The currents low iron glass mirrors are one of the
most reliable components in the Luz collectors.
• Mirrors breakage due to high winds has been
observed near the edegs of the solar field where
wind forces can high

9. FLEXHOSES
The flexhoses that connects the SCAs to the headers
& SCAs to each others have experienced high
failure rates at the early SEGs plants

10. MIRRORS WASHING &
REFLECTING MONITIRNG
• Devlopment of an efficient & cost effective
program for monitoring mirror reflectivity &
washing mirrors is critical.
• The period monitiring of mirror reflectivity can
provide a valuable quality control tool for mirror
washing & help optimize wash labor.

11. MAINTENANCE TRACKING
• In recent years, computrized maintenance
management software(cmms) has found wide
acceptance for use in conventional fossil power
plant.
• CMMS programs have been implemented at
through power plants as well but the software not
ideally used.

12. COLLECTOR ALIGNMENT
Operational experience has that it is important to be
able to periodically check collecors alignment & to be
able to correct alignment problems when necessary

13. PARABOLIC DISH/ENGINE
• The dish/engine system is a concentrating solar
power (CSP) technology that produces relatively
small amounts of electricity compared to other CSP
technologies—typically in the range of 3 to 25
kilowatts.
• Dish/engine systems use a parabolic dish of mirrors
to direct and concentrate sunlight onto a central
engine that produces electricity.
• The two major parts of the system are :-
SOLAR CONCENTRATOR
POWER CONVERSION UNIT.

15. SOLAR CONCENTRATOR
• The solar concentrator, or dish, gathers the solar
energy coming directly from the sun.
• The resulting beam of concentrated sunlight is
reflected onto a thermal receiver that collects the solar
heat.
• The dish is mounted on a structure that tracks the sun
continuously throughout the day to reflect the highest
percentage of sunlight possible onto the thermal
receiver

16. POWER CONVERSION UNIT
• The power conversion unit includes the thermal
receiver and the engine/generator.
• The thermal receiver is the interface between the dish
and the engine/generator. It absorbs the concentrated
beams of solar energy, converts them to heat, and
transfers the heat to the engine/generator.

17. • The engine/generator system is the subsystem that
takes the heat from the thermal receiver and uses it to
produce electricity.
• The most common type of heat engine used in
dish/engine systems is the Stirling engine.
• A Stirling engine uses the heated fluid to move
pistons and create mechanical power. The mechanical
work, in the form of the rotation of the engine's
crankshaft, drives a generator and produces electrical
power.

18. ADVANTAGES PARABOLIC
DISH
• Solar farm can be placed in hot, dry inhospitable
location where human & wildlife s sparse
• The entire system uses established technology that is
readily available

19. POWER TOWER SYSTEM

20. • Solar power towers generate electric power from sunlight by
focusing concentrated solar radiation on a tower-mounted heat
exchanger (receiver). The system uses hundreds to thousands of
sun-tracking mirrors called heliostats to reflect the incident
sunlight onto the receiver. These plants are best suited for utility-
scale applications in the 30 to 400 Mwe range.
• In a molten-salt solar power tower, liquid salt at 290ºC (554ºF)
is pumped from a ‘cold’ storage tank through the receiver where it
is heated to 565ºC (1,049ºF) and then on to a ‘hot’ tank for storage.
When power is needed from the plant, hot salt is pumped to a
steam generating system that produces superheated steam for a
conventio- nal Rankin cycle turbine/generator system. From the
steam generator , the salt is returned to the cold tank where it is
stored and
eventually reheated in the receiver.

21. ADVANTAGE
• Capital costs for the solar turbine are reduced
because only an increment to the base-load fossil
turbine must be purchased;
• O&M costs are reduced because only an increment
beyond the base-load O&M staff and materials must
be used to maintain the solar-specific part of the
plant; and,
• The solar plant produces more electricity because the
turbine is hot all the time and daily start-up losses

22. BENIFITS OF CSP
• CSP can yield more than plentiful ,inexhaustible &
secure of pollution-free electricity.
• Description of sea water & air conditioning.
• Protection from direct tropical sunlight.
• New industries, new jobs & new sources of incomes.
• Social sustainability
• Economic sustainability

23. SCOPE OF SOLAR POWER IN
INDIA
• The vast RAJASTAN DESERT is very similar to the
SAHARA DESERT in AFRICA has the largest power
in INDIA.
• Solar power can also reduce strain on the electric grid
on hot summer afternoon's.
• Place at BHOPAL & NAGPUR have been identified
to start concentrated solar power plant project.

24. CONCLUSION
• Solar power is an enormous readily available source
of energy.
• It can be used everywhere & can in principal satisfy
most of INDIA’s energy demand from a renewable,
safe & clean resource
