As the human population increases, our rate of consumption of these fossil fuels also increases. On the other hand, world population continues to grow and the limited amount of fossil fuels begin to diminish, it may not be possible to provide the amount of energy demanded by the world by only using fossil fuels to convert energy. The solution to the problems of limited fossil fuels and their impact on the environment is to have renewable resources play a larger role in the supply of energy. In this case wind energy is the most promising green energy. As wind turbine output is proportional to the cube of wind speed, the wind turbine generator output fluctuates due to wind speed variation. Thus this paper focuses on the comparative study between conventional wind turbine models with modified pitch controller and proposed a new technique called modified pitch governor with exciter controller to control output voltage and frequency without using any costly energy storage devices. In this study variable load is considered and real wind speed data is taken to obtain realistic response. PSCAD/EMTDC software is used for simulation analyses.","PeriodicalId":6578,"journal":{"name":"2016 2nd International Conference on Electrical, Computer & Telecommunication Engineering (ICECTE)","volume":"11 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86615217","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}

Among the various renewable resources, wind energy is one of the most important and promising sources. In the recent year doubly fed induction generator (DFIG) is one of the most widely used in wind farms. But the transient stability of DFIG becomes very much sensitive and challenging concern. Three phase line-to-ground fault (3LG) is one of the worst cases of DFIG. During fault at grid side, DFIG is much affected because its stator windings are directly connected to grid. So it is important to analyse the transient stability of DFIG during fault according to fulfil the grid code requirement. To improve the transient stability and fault ride through capability of DFIG a new topology of fault current limiter (FCL) is proposed in this paper. The proposed FCL is not only limit the fault current but also faster voltage recovery. Thus improve the transient stability and fulfil the grid code requirements. For simulation analysis, PSCAD/EMTDC software is used. To determine the advantageousness of proposed FCL, its performance is compared with the conventional series dynamic resistor (SDR). Simulation results show that the proposed FCL enhances the transient stability of DFIG and better performance than SDR.","PeriodicalId":6578,"journal":{"name":"2016 2nd International Conference on Electrical, Computer & Telecommunication Engineering (ICECTE)","volume":"175 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76965227","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}

Mostly used human biometrics are face, fingerprint, iris, gait, retina, voice, hand geometry etc. Among them iris is an externally visible, yet protected organ whose unique epigenetic pattern remains stable throughout one's whole life. These characteristics make it very attractive to use as a biometric for identifying individuals. This paper presents a detailed study of iris recognition technique. It encompasses an analysis of the reliability and the accuracy of iris as a biometric of person identification. The main phases of iris recognition are segmentation, normalization, feature encoding and matching. In this work automatic segmentation is performed using circular Hough transform method. Daugman's rubber sheet model is used in normalization process. Four level phase quantization based 1D Log-Gabor filters are used to encode the unique features of iris into binary template. And finally the Hamming distance is considered to examine the affinity of two templates in matching stage. We have experimented a better recognition result for CASIA-iris-v4 database.","PeriodicalId":6578,"journal":{"name":"2016 2nd International Conference on Electrical, Computer & Telecommunication Engineering (ICECTE)","volume":"25 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90074305","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}

Cadmium Sulfide (CdS) and Indium Sulfide (In<inf>2</inf>S<inf>3</inf>) buffer layer based Copper Indium Gallium Selenide (CIGS) solar cell offers higher efficiency with low manufacturing cost. Therefore, this paper presents a comparative study between CdS and In<inf>2</inf>S<inf>3</inf> buffer layer based CIGS solar cell. The numerical study has been performed using a Solar Cell Capacitance Simulator named SCAPS-1D. The performance of CIGS solar cell is observed by adjusting the buffer layer thickness of both CdS and In<inf>2</inf>S<inf>3</inf>. The efficiency of CdS/CIGS solar cell is found 25.56% that is higher than the efficiency of In<inf>2</inf>S<inf>3</inf>/CIGS (24.41%) solar cell for 50 nm buffer layer thickness. It is also found that, the increase in buffer layer thickness from the optimum level degrades the performance of CdS/CIGS solar cell as compared to In<inf>2</inf>S<inf>3</inf>/CIGS solar cell. Therefore, In<inf>2</inf>S<inf>3</inf> based CIGS cell could be an ideal candidate as a substitute of toxic CdS buffer layer based CIGS solar cell.","PeriodicalId":6578,"journal":{"name":"2016 2nd International Conference on Electrical, Computer & Telecommunication Engineering (ICECTE)","volume":"6 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87505505","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}
