The existing IG based farms create a huge problem especially in case of expanding the capacity of the wind farm. This paper introduces a new solution for the problem. It suggests that the introduction of permanent magnet synchronous generator (PMSG) with IG, not only expands the capacity of the wind farm, but also it produces a stable output. A practical case considering Synchronous Generator (SG) in combination with a wind farm having both IG and PMSG has been used. The proposed PMSG has been equipped with the full-rated power converters. The results prove the effectiveness of the proposed model. Simulations have been done by using the engineering software PSCAD/EMTDC.

GPS module provides geographic coordinates at regular time intervals. Then the GSM module transmits the location of vehicle to cell phone of owner/user in terms of latitude and longitude. At the same time, location is displayed on LCD. Finally, Google map displays the location and name of the place on cell phone. Thus, owner/user will be able to continuously monitor a moving vehicle using the cell phone.

Conventional switching-table-based single-vector DPC (SV-DPC) presents irregular power ripples and variable switching frequency, due to the use of predefined switching table and hysteresis comparators. To solve these problems, two-vector DPC (TV-DPC) and three-vector DPC (THV-DPC) based three-phase pulse width modulation (PWM) rectifier are proposed. Although the performance of the THV-DPC is better than that of TV-DPC, its algorithm implementation is very complex and time consuming. In this paper, two-three combined vector DPC (TTCV-DPC) algorithm is presented which combines two and three voltage vectors by the help of the new switching table. The proposed algorithm has less complexity than the THV-DPC and better performance than the TV-DPC. Comprehensive simulations demonstrate the proposed method can get lower power ripple and lower grid-side current total harmonic distortion (THD) than that of TV-DPC.","PeriodicalId":6578,"journal":{"name":"2016 2nd International Conference on Electrical, Computer & Telecommunication Engineering (ICECTE)","volume":"53 12 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":"85692100","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}

Each of the stages in the auxiliary stages consists of three H-bridge where the H-bridge cells contain isolated DC power supplies.

Fresnel's four layer model has been used here for analyzing the performance parameters of SPR biosensor. The analysis shows that Surface Plasmon Resonance Frequency (SPRF) increases with the increasing concentration of target molecule for every graphene layer. It is found that the sensitivity curve for different graphene layer with respect to conventional SPR biosensor is non-linear. How the sensitivity increases with increasing graphene layer was studied in this work. The basic polynomial fitting is used and found that sensitivity increases nonlinearly with the increasing layers and the degree of nonlinearity also increases.","PeriodicalId":6578,"journal":{"name":"2016 2nd International Conference on Electrical, Computer & Telecommunication Engineering (ICECTE)","volume":"4 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":"87841357","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}

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.
