Performance Acceptance Test Guidelines ’Name of Author : ‘’Name of Journal/Publication: ‘ David Kearney’Published Year : ‘2013’Objectives: Methodology: 1. To provide Acceptance Test Guidelines for the

solar systems of power tower plant. 2.To measure the thermal power output of the

solar system under clear-sky conditions Result & Concluding Remarks: It has been concluded that various

second-order effects on equipment's such as the heliostat, receiver, the thermal energy storage systems ( SET) could affect the performance of plant


Literature Review-Paper 3Title of Research Paper : ‘ Optimal heliostat aiming strategy for uniform

distribution of heat flux on the receiver of a solar power tower plant’Name of Author : ‘ Saeb M. Besarati, D. Yogi Goswami, elias K.

Name of Journal/Publication: ‘ ELSEVIER ’Published Year : ‘ 2014 ’Objectives: To minimize the standard deviation of the flux density

distribution by changing or aiming points of individual heliostats.Methodology: Flux distribution of each heliostat is found by using the

HFLCAL model.Result & Concluding Remarks: After employing the new algorithm the

maximum flux density is reduced by an order of magnitude.Dr. D. Y. Patil School of Engineering,Lohegaon, Pune. 4

Literature Review-Paper 4Title of Research Paper : ‘ Energy and exergy analysis of a

closed Brayton cycle-based combined cycle for solar power tower plants. ’Name of Author : ‘ V. Zare, M. Hasanzadeh ’

Name of Journal/Publication: ‘ ELSEVIER ’

Published Year : ‘ 2016 ’

Objectives: To employ an efficient thermodynamic power cycle.

Methodology: In these they use a two closed Brayton cycle, and extra two organic Rankine cycle in order to recover the waste heat of Brayton cycle

Result & Concluding Remarks: The overall efficiency of the system is increased by 30%, and also the power cycle proposed in this work has a better performance than the other cycles.

• World Energy Conservation predicted estimation about the rate of utilization of energy resources shows that the coal coal depositsdeposits will deplete within the next 200200 to 300300 years and petroleum depositspetroleum deposits will deplete in next few decadesnext few decades

• The most advantage using Solar EnergySolar Energy is that this is distributed over a wide geographical area, ensuring that developing regions such as IndiaIndia have access to electricity generation at a stable cost for the long-term future

• The huge consumption of fossil fuels has caused visible damage to the environment in various forms

Why Solar EnergyWhy Solar Energy


Importance of Solar Energy Importance of Solar Energy

The following table shows the amount of carbon and sulphur deposited in the atmosphere

S. No Activity Amount deposited in the atmosphere

1. Human Vehicle, Waste product etc 8 billion tones

2. Fossil fuels 6.5 million tones

3. Deforestation and forest firing 1.5 million tones

At present so many alternative fuels have been developed, still they are able to meet only a small proportion of our actual demand - The right fuel mixThe right fuel mix



Current solar energy consumption


INTRODUCTION:


TYPES :


1. Linear concentrator Collects the sun's energy using long rectangular, curved (U-shaped) mirrors.

The reflected sunlight heats a fluid flowing through the tubes.

The hot fluid then is used to boil water in a conventional steam-turbine generator to produce electricity.

There are two major types of linear concentrator Systems :

>> Parabolic trough systems and

>> Linear Fresnel reflector systems.


2. Dish/engine Uses a mirrored dish similar to a very large satellite dish.

The dish-shaped surface directs and concentrates sunlight onto a thermal receiver, which absorbs and collects the heat and transfers it to the engine generator.

The most common type of heat engine used today in dish/engine systems is the Stirling engine.

The mechanical power is then used to run a generator or alternator to produce electricity.


3. Power tower systems Uses a large field of flat, sun-tracking mirrors known as heliostats to focus and concentrate sunlight onto a receiver on the top of a tower.

A heat-transfer fluid heated in the receiver is used to generate steam.

Some power towers use The energy-storage capability, or thermal storage, allows the system to continue to dispatch electricity during cloudy weather or at night.

Basic Design Of CSP Plant



Working/ Operation of Plant



ADVANTAGES :


IDEAL PLACES FOR CSP :

The desert regions of Australia and Africa.

Mediterranean regions, with frequent sunshine.

In INDIA, places like Gujarat & Rajasthan etc..,

Questions



Earth receives around 174 Petawatts of energy from sun and only a small part of it is sufficient to meet the annual world electricity consumption of 20 Trillion kWh

We Just need to tap this potential
