A stack of substrate is formed from two different dielectric substrate materials, each of equal height. The performance of the designed antenna is investigated for three different substrate stacks such as Quartz-Silicon, GaAs-Silicon Nitride, and Polyimide-Glass. For each stack, total substrate height is varied from 80 μm to 120 μm, taking 20 μm as step size. The considered performance parameters of the designed antenna are return loss, bandwidth, radiation efficiency, gain, and directivity at a targeted resonance frequency of 1.02 THz. The simulation results confirm that Quartz-Silicon substrate pair with a height of 100 μm provides the best antenna performance. The enhanced outcomes are compared with other similar graphene antennas to ensure the effectiveness of the proposed design. The attractive properties and significant performances of the proposed graphene antenna make it a potential candidate to be used in wireless communication in nanosystems and THz sensing applications.","PeriodicalId":6578,"journal":{"name":"2016 2nd International Conference on Electrical, Computer & Telecommunication Engineering (ICECTE)","volume":"14 3 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":"82680109","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 has been observed that electrodes of different compositions such as: TiO2 and ZnO, surface morphology of the thin films used in SSDSSCs, use of different types of dyes as photo sensitizers, use of Nanorods/Nanoparticles as photoanodes — all correspond to different photoelectric conversion efficiencies (PCEs) in SSDSSCs. As the SSDSSCs are free of leakage and corrosion related problems prevalent in conventional liquid-based Dye Sensitized Solar Cells (DSSCs), it has the potential to lower the maintenance cost and improving longevity of a system, so far however SSDSSCs suffer from low PCEs when compared with conventional DSSCs, with a maximum efficiency record of approximately 15 per cent set in 2013 by using solid-state mesoscopic TiO2 solar cells sensitized with lead iodide perovskite (CH3NH3PM3) pigments[1–4], in early 2014 which was further lifted to 16.7 per cent[26]. Careful selection of highly photosensitive dye in conjunction with proper nanotube photonic crystals can optimize the efficiency of SSDSSCs for the intertropicsl region.","PeriodicalId":6578,"journal":{"name":"2016 2nd International Conference on Electrical, Computer & Telecommunication Engineering (ICECTE)","volume":"24 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":"86942911","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}

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}
