The Newton-Raphson three-phase power flow algorithm has been suitably modified to incorporate the model of a Doubly Fed Induction Generator (DFIG). Various modes of operation of the DFIG have been modeled along with applicable operating constraints. The operation of the DFIG may be restricted within allowable limits due to large unbalance in the distribution system. Thus, a novel strategy for enforcing limits is proposed and comparative results with method available in literature are illustrated on IEEE 123 bus distribution system. Moreover, computational burden is also compared for different IEEE distribution systems.","PeriodicalId":283953,"journal":{"name":"2016 IEEE Annual India Conference (INDICON)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116816284","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 found that there is a slight degradation in the performance of the antenna when the superstrate is touching the antenna i.e height of the superstrate above the EMD (H =0 mm). Further, it is also observed that the degraded performance characteristics of the EMD antenna can be improved by placing the dielectric superstrates above the EMD at optimum height (H) = Hopt. The EMD antenna without dielectric superstrate achieves an impedance bandwidth of 3.354 GHz (SWR< 2) at 3.20 GHz, and loaded with dielectric superstrates which shows that the resonate frequency is decreased and achieved impedance bandwidth is 3.351GHz (SWR< 2) at 3.37 GHz. As the dielectric constant of the superstrate increases, it has been observed that the center frequency 3.39 GHz and gain is decreased to 7.40 dB from 7.52 dB. As the height of the superstrate is increased the performance of the antenna improves and at particular optimum height, the gain and bandwidth for all the superstrates will be closer to the free space radiation conditions of the EMD antenna without superstate. However, the return-loss for all dielectric constants of the superstrates is more than −18.60 dB which is well above the acceptable limit. The variation in return-loss is within acceptable limits. This antenna is stable radiation pattern with low cross polarization, low back radiation, nearly identical E- and H-plane patterns. There is a good agreement between simulated and measured results.","PeriodicalId":283953,"journal":{"name":"2016 IEEE Annual India Conference (INDICON)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128494647","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 wavelength shifts related to attenuation dips are highly sensitive to salinity of sea water when CO laser is used as the source. Using simple and robust schematic design, sensitivity of 0.01pm/ppt is achieved for salinity range of 31 to 37 ppt at a constant temperature of 27°C.

Phylogenetic trees have been constructed to provide a visual understanding of the same. The results obtained match with already existing knowledge about language families. For all types of linkage measures, the closest language to Hindi is Marathi and for Tamil, it is Telugu. Since K-medoids give expected language relationships, they are used to learn dictionaries in order to see if they are useful in language identification as well. We have reported the results of one-vs-one classification and found that accuracy improves in the case of English when the weights recovered are multiplied with joint probability of the cluster associated with that medoid.","PeriodicalId":283953,"journal":{"name":"2016 IEEE Annual India Conference (INDICON)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129454561","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}

The output of the existing anti-differential Hall-Effect current sensor is highly sensitive to the distance between the conductor and the Hall Effect sensors. This distance is a function of the thickness of the insulation and it vary from wire to wire. Non-uniformity of the insulation is also a factor. Another issue of anti-differential system is that the conductor should be kept exactly at the middle of the two Hall sensors. These factors are always prone to introduce errors in the output, and in some cases it can be of unacceptable error range. The proposed scheme is a modified version of the anti-differential configuration. The scheme is modified such that the output is not dependent on the distance between the conductor and the Hall Effect sensors, also the conductor need not be exactly at the middle of the sensors. This approach enables easy manufacturing and installation of the system and avoids the errors due to the above listed factors that otherwise affect the output. Finite Element Method (FEM) studies have been conducted to evaluate the functionality of the proposed method. A prototype of the proposed scheme has been developed and tested in the laboratory, in detail. The prototype developed has all the positive points mentioned above, in addition, it is compact, and retains all the benefits of the coreless Hall-Effect based current sensors. The proposed current sensing scheme will have number of applications in power system, machine monitoring, metering, etc.","PeriodicalId":283953,"journal":{"name":"2016 IEEE Annual India Conference (INDICON)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129906651","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 paper presents an innovative solution to develop on-line monitoring technology to promote overall plant health, detect incipient problems, and improve operations and maintenance productivity.
