A solar power plant is based on the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses, mirrors, and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics converts light into electric current using the photoelectric effect. The largest photovoltaic power plant in the world was the 354 MW Solar Energy Generating Systems (SEGS) CSP installation located in the Mojave Desert, California. But now the largest is in india, India owns world's largest solar power plant - Believe it or not | The Economic ... Other large CSP plants include the 250 MW Agua Caliente Solar Project in Arizona, the Solnova Solar Power Station (150 MW, 250 MW when finished) and the Andasol solar power station (150 MW), both in Spain.
Concentrated solar power plants first appeared in the 1980s. Solar power is increasingly used.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

2. INTRODUCTION
Solar thermal power generation systems use mirrors to collect
sunlight.
It produces steam by solar heat to drive turbines for generating power.
This system generates power by rotating turbines like thermal and
nuclear power plants.
It is suitable for large-scale power generation.
3. SOLAR POWER GENERATIONS
There are two main ways of generating energy from the sun.
Photovoltaic (PV) Concentrating Solar Thermal(CST)
Converts sunlight directly
into electricity.
Generates electricity indirectly.
4. SOLAR THERMAL SYSTEMS
There are two types of solar thermal systems:
Passive: A passive system requires no equipment, and rely on design features
only to capture heat.
(e.g. green houses).
Active : An active system requires some way to absorb and collect solar radiation
and then store it.
(e.g. Solar thermal power plants).
5. BASIC WORKING PRINCIPLE
Mirrors reflect and concentrate sunlight.
Receivers collect that solar energy and convert it into heat energy.
A generator can then be used to produce electricity from this heat
energy.
6. TYPES OF SOLAR THERMAL POWER PLANTS
1.Parabolic trough system 2.Solar power tower systems 3.Solar dish/engine system
4.Compact linear Fresnel reflector
7. PARABOLIC TROUGH SYSTEM
A parabolic trough consists of a linear parabolic reflector that
concentrates light onto a receiver positioned along the reflector's focal
line.
The receiver is a tube positioned directly above the middle of the
parabolic mirror and filled with a working fluid.
The reflector follows the sun during the daylight hours by tracking
along a single axis.
A working fluid (e.g. molten salt) is heated to 150–350 °C (423–623
K (302–662 °F)) as it flows through the receiver and is then used as a
heat source for a power generation system.
10. SOLAR POWER TOWER SYSTEMS
These designs capture and focus the sun's thermal energy with
thousands of tracking mirrors (heliostats) in roughly a two square mile
field.
A tower resides in the center of the heliostat field. The heliostats focus
concentrated sunlight on a receiver which sits on top of the tower.
Within the receiver the concentrated sunlight heats molten salt to over
1,000 °F (538 °C).
The heated molten salt then flows into a thermal storage tank where it
is stored, maintaining 98% thermal efficiency, and eventually pumped
to a steam generator.
The steam drives a standard turbine to generate electricity.
13. SOLAR DISH/ENGINE SYSTEM
The system consists of a stand-alone parabolic reflector that concentrates
light onto a receiver positioned at the reflector's focal point.
The working fluid in the receiver is heated to 250–700 °C (523–973 K
(482–1,292 °F)) and then used by a Stirling engine to generate power.
Parabolic-dish systems have the highest efficiency of all solar
technologies provide solar-to-electric efficiency between 31–32%.
Stirling Engine
16. COMPACT LINEAR FRESNEL REFLECTOR
Linear Fresnel reflectors use long, thin segments of mirrors to focus
sunlight onto a fixed absorber located at a common focal point of the
reflectors.
These mirrors are capable of concentrating the sun’s energy to
approximately 30 times its normal intensity.
This concentrated energy is transferred through the absorber into some
thermal fluid.
The fluid then goes through a heat exchanger to power a steam
generator.
18. ADVANTAGES OF SOLAR THERMAL ENERGY
No Fuel Cost.
Predictable, 24/7 Power.
No Pollution and Global Warming Effects.
Renewable Energy Source
Low Maintenance Costs.
19. DISADVANTAGES OF SOLAR THERMAL ENERGY
High Cost
Water Issue.
Limited Locations and Size Limitations
Long Gestation Time Leading to Cost Overruns
20. MAJOR CHALLENGES
The major challenge are the Installation Cost and energy storage.
The costs are still far higher than fossil fuel plants based on units of
energy produced.
The hot water storage products are often stretched to their limits.
Alternatives could be phase change materials (PCMs) or thermo-
chemical materials (TCMs).
In addition to sensible heat, the technologies of latent heat and
thermo-chemical energy storage are on their way to becoming very
promising solutions for the future of solar heating and cooling.
21. CONCLUSION
In the face of global warming, rising fuel costs and an ever-growing
demand for energy, energy needs are expected to increase by nearly
the equivalent of 335 million barrels of oil per day, mostly for
electricity.
By concentrating solar energy with reflective materials and converting
it into electricity, modern solar thermal power plants, if adopted today
as an indispensable part of energy generation, may be capable of
sourcing electricity to more than 100 million people in the next 20
years..
