{"title":"Comparison of GDC electrolyte-LSCF cathode IT-SOFC system with conventional power sources","authors":"D. S. Gyan, R. Gupta, P. Roy","doi":"10.1109/ENERGYECONOMICS.2015.7235109","DOIUrl":"https://doi.org/10.1109/ENERGYECONOMICS.2015.7235109","url":null,"abstract":"Remarkably high electrical efficiency at attractive economics can be achieved by using Ce_0.8Gd_1.2O_1.2 (Gadolinium Doped Ceria (GDC)) as solid electrolyte in IT-SOFC (Intermediate Temperature-Solid Oxide Fuel Cell) and using La_1-xSr_xCo_1-yFe_yO_3-δ (LSCF) as cathode where, 0 <; x ≤ 0.5, 0 <; y ≤0.8. Different solid oxide electrolyte samples were synthesized employing dry pressing technique, thereafter the samples were sintered at different temperatures ranging from 1350°C to 1600°C. Relative density as high as 93.93% was achieved for electrolyte samples. X-Ray Diffraction (XRD) pattern for sintered GDC samples reveals the presence of crystalline crystallographic system of cubic phases with crystal orientation such as (111), (200), (220), (311), (222), (400), (331), (420), thereby ensuring productive sintering. Impedance Analysis at different temperatures indicates that the ionic conductivity increases with the increase in sintering temperature and was found to attain its peak value at 1550 °C. Exceptionally high power density of 347mW/cm², 539mW/cm² and 747mW/cm² of 700 °C, 750°C and 800 °C were achieved indicating excellent electrolytic performance. This justified the competency of GDC to replace conventional YSZ (Yttrium Stabilized Zirconia) electrolyte. Further, different cathode samples were synthesized using combustion synthesis technique, thereafter the samples were sintered at different temperatures ranging from 1050°C to 1150°C for 4 hours in air. Single phase rhombohedral of LSCF is obtained and is confirmed by the peaks corresponding to (104), (110), (024), (300) and (306). Surface area of the sample having highest cobalt concentration is found to be much higher than other samples, that is, 14.579 m²/g. TG graphs shows that drastic weight loss occurs in three steps in the temperature range of 195-200 °C, 300-340 °C and 430-460 °C. Arrhenius plot suggests that DC conductivity increases with increase in densification for sample having lowest cobalt concentration while decreases in case of other samples, Of all the prepared samples, La_0.54Sr_0.4Co_0.8Fe_0.2O_3±δ was found to be most efficient as it achieved current density as high as 2.12A/cm² at 800 °C under cell operation voltage of 0.7 V. Hence the GDC electrolyte and LSCF cathode IT-SOFC fuel cell system can deliver attractive economics and consequently can be used for the production of clean energy allowing sustainable development.","PeriodicalId":130355,"journal":{"name":"2015 International Conference on Energy Economics and Environment (ICEEE)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129556352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper investigates the effectiveness of different methods for optimal allocation and sizing of DGs in autonomous and non-autonomous micro-grid modes based on the voltage profile, power losses, total DG size and reliability. In the proposed work initially, an effective power flow based loss sensitivity factor (LSF) method and active power injection based LSF method for DG allocation are compared in non-autonomous micro-grid mode. After siting DGs, LSF based optimal sizing has been executed in non-autonomous mode micro-grid operation. Later, the micro-grid has been converted into autonomous mode based on the optimal sizing and siting of DGs in non-autonomous mode operation. Additionally, the obtained results have been improved by PSO-TVIW based sizing method. The proposed methodology is adopted in standard IEEE 33 bus radial system which has been converted into autonomous micro-grid for verification.","PeriodicalId":130355,"journal":{"name":"2015 International Conference on Energy Economics and Environment (ICEEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131130368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In frequency domain spectroscopy, dielectric response current is measured for a period of two cycles over a wide range of frequencies. Such measurements on real life transformers take long time in practice especially in the lower frequency range which is practically problematic. Considering the above-said fact, a new technique has been developed in the present work that can reduce the measurement time significantly. Instead of using the excitation for two cycles, quarter cycle of the excitation is applied on insulation under test. The method is verified on three test samples having different preset moisture contents. The dielectric dissipation factors of the test samples computed from the proposed method, are then compared with the corresponding values calculated for two cycles of the applied excitation. The results show negligible differences in the values of dissipation factors of the test samples obtained with the applied excitation for two cycles with that of quarter cycle.","PeriodicalId":130355,"journal":{"name":"2015 International Conference on Energy Economics and Environment (ICEEE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126797290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here two systems, real time and off line, are proposed to monitor the temperature variations and analyze the hot regions beyond the rated temperature in the three phase induction motor using infrared thermograms. This system helps to monitor the variation of temperature at the different parts of the induction motor. Abnormal temperature rise in any parts indicates the faults. This technique helps to prevent the parts of induction motor before any catastrophe would happen in the future. The color based segmentation technique is used to identify abnormal hot regions in the thermograms of three phase induction motor. A changing red color intensity algorithm is also implemented to recognize the hot spots and also the change in hotness in a particular area of induction motor to declare the health of that particular area. Similarly the conditions of various areas in the machine all together monitor the overall health of the Induction motor.","PeriodicalId":130355,"journal":{"name":"2015 International Conference on Energy Economics and Environment (ICEEE)","volume":"215 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116601232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Doja, Bashir Alam","doi":"10.1109/ENERGYECONOMICS.2015.7235092","DOIUrl":"https://doi.org/10.1109/ENERGYECONOMICS.2015.7235092","url":null,"abstract":"Clustering is one of the efficient techniques which not only help in protraction of lifetime of wireless sensor network but also make it scalable and robust. Subdivision of network into group of sensor nodes with a coordinator is called a cluster. Cluster members collect the physical data by sensing the environment and forward it to the coordinator which is generally termed as Cluster Head (CH). This cluster head aggregates the data and transmit it to the Base Station for further processing of data to meet the requirement of the application. In this paper we have proposed a novel self organising clustering scheme which considers the real time parameters for setting up the clusters for data collection. Unlike several proposed algorithm, this scheme reclusters the network only when CH fall below a threshold level. Repeated unnecessary clustering in every round depletes the energy of the network more quickly. We have introduced heterogeneity in the proposed work. By virtue of heterogeneity in terms of energy, lifetime of the network can be extended. An algorithm is functional if the area of interest is covered by active nodes. The period for which the network is functional is termed as persistent period in our paper. Simulation results show that the proposed scheme is comparatively more energy efficient, scalable & robust and has longer persistent period.","PeriodicalId":130355,"journal":{"name":"2015 International Conference on Energy Economics and Environment (ICEEE)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121257402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present paper deals with use of an ELC for synchronous generator of micro hydro power plant of rating 60 KW in MATLAB Simulink. The design of ELC using a controlled bridge rectifier and IGBT chopper feeding a resistive dump load has been implemented for simulation in this paper. The power consumption of chopper has been varied by the duty cycle of the chopper. The simulation results have shown the changes in various parameters, i.e., excitation voltage, stator current, mechanical power output, output power of generator, power across consumer load, and dump load as a result of the change in demand/load.","PeriodicalId":130355,"journal":{"name":"2015 International Conference on Energy Economics and Environment (ICEEE)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125154931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
