modeling and performance simulation of 100 mw ptc based solar Thermal Power Plant in udaipur india
Case Studies in Thermal Engineering, 2017Co-Authors: Deepak Bishoyi, K SudhakarAbstract:Abstract Solar energy is a key renewable energy source and the most abundant energy source on the globe. Solar energy can be converted into electric energy by using two different processes: by means of photovoltaic (PV) conversion and the thermodynamic cycles. Concentrated solar Power (CSP) is viewed as one of the most promising alternatives in the field of solar energy utilization. Lifetime and efficiency of PV system are very less compared to the CSP technology. A 100 MW parabolic trough solar Thermal Power Plant with 6 h of Thermal energy storage has been evaluated in terms of design and Thermal performance, based on the System Advisor Model (SAM). A location receiving an annual DNI of 2248.17 kW h/m 2 in Rajasthan is chosen for the technical feasibility of hypothetical CSP Plant. The Plant design consists of 194 solar collector loops with each loop comprising of 8 parabolic trough collectors. HITEC solar salt is chosen as an HTF due to its excellent thermodynamic properties. The designed Plant can generate annual electricity of 285,288,352 kW h with the Plant efficiency of 21%. The proposed design of PTC based solar Thermal Power Plant and its performance analysis encourages further innovation and development of solar Thermal Power Plants in India.

performance assessment of parabolic dish and parabolic trough solar Thermal Power Plant using nanofluids and molten salts
International Journal of Energy Research, 2016Co-Authors: Muhammad Abid, Tahir Abdul Hussain Ratlamwala, Ugur AtikolAbstract:Summary The present study has been conducted using nanofluids and molten salts for energy and exergy analyses of two types of solar collectors incorporated with the steam Power Plant. Parabolic dish (PD) and parabolic trough (PT) solar collectors are used to harness solar energy using four different solar absorption fluids. The absorption fluids used are aluminum oxide (Al2O3) and ferric oxide (Fe2O3)-based nanofluids and LiCl-RbCl and NaNO3-KNO3 molten salts. Parametric study is carried out to observe the effects of solar irradiation and ambient temperature on the parameters such as outlet temperature of the solar collector, heat rate produced, net Power produced, energy efficiency, and exergy efficiency of the solar Thermal Power Plant. The results obtained show that the outlet temperature of PD solar collector is higher in comparison to PT solar collector under identical operating conditions. The outlet temperature of PD and PT solar collectors is noticed to increase from 480.9 to 689.7 K and 468.9 to 624.7 K, respectively, with an increase in solar irradiation from\ 400 to 1000 W/m2. The overall exergy efficiency of PD-driven and PT-driven solar Thermal Power Plant varies between 20.33 to 23.25% and 19.29 to 23.09%, respectively, with rise in ambient temperature from 275 to 320 K. It is observed that the nanofluids have higher energetic and exergetic efficiencies in comparison to molten salts for the both operating parameters. The overall performance of PD solar collector is observed to be higher upon using nanofluids as the solar absorbers. Copyright © 2015 John Wiley & Sons, Ltd.

effects of the selection of heat transfer fluid and condenser type on the performance of a solar Thermal Power Plant with technoeconomic approach
Energy Conversion and Management, 2016Co-Authors: Zeki M YilmazogluAbstract:Abstract Renewable electricity generation systems have an increasing trend in terms of usage due to aiming to decrease greenhouse gas emissions and energy source diversification strategies of countries. Parabolic trough, Fresnel, and solar tower systems have been used to generate solar Thermal electricity around the world. In this study, the effects of the selection of collector heat transfer fluid (HTF) and condenser type on a concentrated solar Thermal Power Plant were analyzed. Net Power, net electrical efficiency, and economic analysis were carried out for the selected HTFs for different collector outlet temperature cases. In the case of condenser type selection four different systems were considered; water cooled, air cooled (dry air) and air cooled with water spraying (spraying before fan and spraying before and after fan). Levelized cost of energy (LCOE) and specific investment cost were calculated. According to the results, specific investment cost and LCOE were found to be 4000 USD/kW el and 0.207 USD/kW h, respectively. Carbon tax/credit was also included to the calculations of LCOE and a comparison study was carried out for gas turbine, combined cycle and solar Thermal Power Plant with Thermal storage. Including carbon tax/credit to the LCOE shows that solar Thermal Power Plant with heat storage can be competitive when compared to gas turbines.

exergy analysis of a coal based 210 mw Thermal Power Plant
International Journal of Energy Research, 2007Co-Authors: S Sengupta, Amitava Datta, S DuttaguptaAbstract:In the present work, exergy analysis of a coal-based Thermal Power Plant is done using the design data from a 210 MW Thermal Power Plant under operation in India. The entire Plant cycle is split up into three zones for the analysis: (1) only the turbo-generator with its inlets and outlets, (2) turbo-generator, condenser, feed pumps and the regenerative heaters, (3) the entire cycle with boiler, turbo-generator, condenser, feed pumps, regenerative heaters and the Plant auxiliaries. It helps to find out the contributions of different parts of the Plant towards exergy destruction. The exergy efficiency is calculated using the operating data from the Plant at different conditions, viz. at different loads, different condenser pressures, with and without regenerative heaters and with different settings of the turbine governing. The load variation is studied with the data at 100, 75, 60 and 40% of full load. Effects of two different condenser pressures, i.e. 76 and 89 mmHg (abs.), are studied. Effect of regeneration on exergy efficiency is studied by successively removing the high pressure regenerative heaters out of operation. The turbine governing system has been kept at constant pressure and sliding pressure modes to study their effects. It is observed that the major source of irreversibility in the Power cycle is the boiler, which contributes to an exergy destruction of the order of 60%. Part load operation increases the irreversibilities in the cycle and the effect is more pronounced with the reduction of the load. Increase in the condenser back pressure decreases the exergy efficiency. Successive withdrawal of the high pressure heaters show a gradual increment in the exergy efficiency for the control volume excluding the boiler, while a decrease in exergy efficiency when the whole Plant including the boiler is considered. Keeping the main steam pressure before the turbine control valves in sliding mode improves the exergy efficiencies in case of part load operation. Copyright © 2006 John Wiley & Sons, Ltd.

parabolic trough solar Thermal Power Plant simulation scheme multi objective genetic algorithm calibration and validation
Solar Energy, 2012Co-Authors: Javier Bonilla, Luis J Yebra, Sebastian Dormido, Eduardo ZarzaAbstract:Abstract The dynamic simulator design and development of a direct steam generation parabolic-trough solar Thermal Power Plant is detailed in this paper. The dynamic simulator is not only the equation-based object-oriented model but also includes features to facilitate the simulation process. A whole simulator scheme has been developed for that purpose. This simulator scheme considers the issues of fetching and converting sensors data to model inputs and obtaining suitable initial values for the boundary condition problem in the numerical integration. The calibration and validation processes have been tackled, using Matlab as the primary tool. However, several tools were studied and tested. A multi-objective genetic algorithm approach has been chosen for calibrating the dynamic model.
