The evaporator absorbs heat from heat source and facilitates the evaporation of working fluid, the performance of it has an important influence on ORC system. The working fluid mass velocity is the important parameter for evaporator, the increment of mass velocity can enhance heat transfer coefficient and decrease heat transfer temperature, but it also increases pressure drop and heat transfer area, the selection of working fluid mass velocity is important for ORC system. There has been few studies on the working fluid mass velocity for ORC evaporator. The thermodynamic and economic performance of geothermal water ORC system using R1234ze(E) are analyzed, the working fluid mass velocity influences of evaporator on geothermal water outlet temperature, net power output, thermal efficiency, exergy efficiency and electricity generation cost (EGC) are studied, the optimal mass velocities for maximizing net power output and minimizing EGC are obtained for 373.15–423.15 K geothermal water respectively. The results show increasing mass velocity can increase net power output and exergy efficiency, EGC initially decreases and then increases with increasing mass velocity; optimal mass velocities increase with increasing geothermal water inlet temperature; when geothermal water inlet temperature is 418.15K, the EGC of case 2 can decreases by 22.73% compared with case 1.","PeriodicalId":6536,"journal":{"name":"2018 2nd International Conference on Green Energy and Applications (ICGEA)","volume":"26 1","pages":"28-35"},"PeriodicalIF":0.0,"publicationDate":"2018-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81278574","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 addition, the soundness of the water cycle has been threatened by artificial factors associated with changes in land coverage areas during urban development that result in increases of impermeable layers as well as natural factors associated with changes in the characteristics of rainfall due to abnormal climate; this has been accompanied by the formation of urban heat islands, shortages in the water supply, lowered groundwater levels, and damages from floods. To resolve this issue, it is necessary to develop technologies to build a water cycling system capable of improving the soundness of an urban water cycle based on the systematic use of information technology infrastructure and environmental sensor technologies. As a means of evaluating the soundness of urban water cycles, this study proposed an evaluation equation that can be used to evaluate the water cycle soundness levels of natural and artificial water cycles, undertook quantitative analyses to evaluate the degree to which water cycles have become affected by urbanization and industrialization, and proposed a methodology for ensuring the soundness of the water cycle following urban development.","PeriodicalId":6536,"journal":{"name":"2018 2nd International Conference on Green Energy and Applications (ICGEA)","volume":"120 1","pages":"55-58"},"PeriodicalIF":0.0,"publicationDate":"2018-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77438304","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}

As a key driven country development, electricity has a significant impact to the growth of telecommunication industries. In such situations, it is therefore difficult to guarantee the reliability of the telecommunication network, in particular, the electricity supply for the base transceiver station (BTS). To overcome this shortage, locally available renewable energy sources can be a solution as a power supply for a BTS. This study proposes the use of the integrated photovoltaic (PV) system as a power sources for BTS in the remote and isolated areas where the electricity from the grid is unavailable. The results show that the use of PV system is capable of supplying the electrical load requirement of BTS and is very feasible in financial analysis. The designed PV system output can produce 1.16 kW, while BTS load is 1.15 kW. We found that the integrated PV system is capable of handling BTS load. In economic perspective, the investment cost to deploy PV system is affordable due to the advantage of PV system, which is easy to maintain and operate.","PeriodicalId":6536,"journal":{"name":"2018 2nd International Conference on Green Energy and Applications (ICGEA)","volume":"12 1","pages":"108-112"},"PeriodicalIF":0.0,"publicationDate":"2018-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87932901","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 this study, an artificial neural network (ANN) model was developed for prediction of solar energy potential in Andhra Pradesh (AP) and Telangana state (TS), India (lies between 12°41' and 22°N latitude and 77° and 84°40'E longitude). Standard multilayered, feed-forward, back-propagation neural networks with different architecture were designed using MATLAB. Geographical and meteorological data of 28 locations in AP & TS for period of recent 22 years from the NASA geo-satellite database were used for the training and testing the network. Geographical parameters (latitude, longitude and altitude), meteorological data (mean sunshine duration, mean temperature, mean wind speed, mean relative humidity and mean precipitation) and the month of the year were used as input data, while the monthly mean solar radiation was used as the output of the network. Statistical error analysis in terms of mean absolute percentage error (MAPE) was conducted for testing data to evaluate the performance of ANN model. The results show that the correlation coefficients between the ANN predictions and actual mean monthly global solar radiation intensities for training and testing datasets were higher than 95%, thus suggesting a high reliability of the model for evaluation of solar radiation in locations where solar radiation data are not available.","PeriodicalId":6536,"journal":{"name":"2018 2nd International Conference on Green Energy and Applications (ICGEA)","volume":"29 1","pages":"63-68"},"PeriodicalIF":0.0,"publicationDate":"2018-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85714186","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}

Since the floating wind turbines are economical than gravity based or fixed bottom type wind turbines, offshore wind industry is exploring all possible ways to adopt well established oil and gas floating platform technologies. Unlike fixed bottom wind turbines, floating platform is subjected to complex motions in all 6 degrees of freedom that introduces new challenges in predicting the aerodynamic forces on the rotor. The conventional approach to determine the aerodynamic forces is not applicable for offshore floating turbines that is subjected to hydrodynamic and all other forces. The current study is focused on computationally validating the scaled model of NREL 5MW wind turbine that is experimentally investigated for various frequencies of platform surge motions at University of Strathclyde. The thrust forces and rotor torque are computed by numerically simulation and compared with experimental outcome showing a good agreement in the trend. The minor deviation in the aerodynamic forces is attributed to the higher prediction of lift and drag forces by XFOIL.","PeriodicalId":6536,"journal":{"name":"2018 2nd International Conference on Green Energy and Applications (ICGEA)","volume":"130 1","pages":"176-182"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91530347","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}
