One of the main issues is high sintering temperatures (1500–1600°C), increasing difficulty and cost in the cell fabrication process. To lower the sintering temperature, Fe has been evaluated as a sintering aid for Sm3+ and Nd3+ co-doped ceria electrolyte. The reduction in sintering temperature between Sm<inf>0.1</inf>Nd<inf>0.1</inf>Ce<inf>0.79</inf>Fe<inf>0.01</inf>O<inf>2-δ</inf> and Sm<inf>0.1</inf>Nd<inf>0.1</inf>Ce<inf>0.8</inf> O<inf>2-δ</inf> is as much as 250°. The Sm<inf>0.1</inf>Nd<inf>0.1</inf>Ce<inf>0.79</inf>Fe<inf>0.01</inf>O<inf>2-δ</inf> sintered at an optimal sintering temperature of 1250 °C exhibits the highest grain-boundary conductivity and relative density, which is much higher than that of Sm<inf>0.1</inf>Nd<inf>0.1</inf>Ce<inf>0.8</inf> O<inf>2-δ</inf>. The doping of Fe increases both bulk conductivity and grain boundary conductivity of the SNDC electrolyte. An integrated single cell with Sm<inf>0.1</inf>Nd<inf>0.1</inf>Ce<inf>0.79</inf>Fe<inf>0.01</inf>O<inf>2-δ</inf> electrolyte exhibits a high maximum power density of 458 mWcm−2 at 650°C, which is 20–30% higher than previous reports.","PeriodicalId":123761,"journal":{"name":"2017 2nd International Conference on Power and Renewable Energy (ICPRE)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117238768","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 helps to determine the natural variance/uncertainty in the wind speed, which is very useful for predicting the wind power potential in an area. For this, a huge amount of data is required to be processed (from wind speed sensor measurements) and mathematical algorithms are required for rapid reconstruction of the wind field. The Non-negative Matrix Factorization (NMF) and Principal Component Analysis (PCA) have been presented, which can be applied for reconstructing the wind field around obstruction models using CFD basis. The absolute reconstruction error tends to increase with an increase in the inlet velocity. The relative accuracy of NMF and PCA are subject to the sampling rate of the measurement, but there is no influence on the distribution of the wind speed sensors around the obstructions model (above a sampling rate of 0.05%). By application of these reconstruction models using WSR, it has been concluded that the NMF and PCA can be adequately used to reconstruct the wind field around an obstruction model.","PeriodicalId":123761,"journal":{"name":"2017 2nd International Conference on Power and Renewable Energy (ICPRE)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125101961","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}

It is widely used in power system to test electrical equipment. It is designed and achieved by LabVIEW for intelligent control. The system uses virtual instrument programming LabVIEW 2015 platform to design interactive interface of human-computer. The system has the function of test type choosing, test parameter setting and real-time monitoring. It develops real-time(RT) data acquisition system, and completes the design of voltage and current signal conditioning circuit. In the meanwhile, multisim software is used to simulate the voltage and current signal conditioning circuit. Designing protection circuit of overpressure and overcurrent to improve system reliability, and the hardware control platform of electric control cabinet have been realized.
