In such harsh working conditions, acquiring auxiliary power for such sensor load can harm system reliability if the power is drawn directly from the supply or load lines. This paper proposes a non-intrusive power supply system for the sensor load by harvesting the near field magnetic power from the current enriched supply cables. The size and turn number of the magnetic field harvester coil is calculated and verified by the finite element model. A two stage power conditioning circuit is designed, consisting of a 4X voltage multiplier followed by an energy feed-forward enabled buck converter. The prototype of the energy scavenger is implemented and tested on a current ripple enriched cable; the experimental results indicate that the scavenger can harvest more than 30mW from the power cable with 10kHz 7A RMS ripple component.","PeriodicalId":287863,"journal":{"name":"2016 IEEE International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126175493","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 study focuses on integrating an innovative new design of micro hydropower system called the Gravitational Water Vortex Power Plant into existing water infrastructure. Three types of existing water infrastructure are considered applicable for hydropower integration: irrigation canals, reservoirs and weirs. The theoretical designs for the civil works for the low-head gravitational water vortex power plant integrated into these structures are given and the costs of construction are estimated. A scalable system of 1.6kW is also designed and integrated in an existing irrigation canal for the technical performance evaluation and validate the theoretical economical study. The study concludes that the performance of turbine is mostly suitable for rural electrification and to integrate in cost-effective way, the civil works and installation cost should be greatly reduced.","PeriodicalId":287863,"journal":{"name":"2016 IEEE International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128912084","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}

In the recent past, a lot of research and development has been carried out to enhance the reliability, efficiency and cost effectiveness of power electronics converters in order to increase the conversion efficiency from the PV cells. Thus, this paper presents a modified interleaved Flyback inverter for standalone PV applications. The proposed system is developed by interleaving of three Fly-back cells along with one PV source. The effectiveness of the design have been validated by PV based Fly-back converter simulation model.

However, a peak value of reactor current cannot be captured in the digital controller. In this paper, a digital peak current mode control boost converter with conversion from current to frequency and using a frequency detector for a peak current detection in real time is presented.

Usually the power curve satisfies this objective but its use in real-time for the detection of abnormal performance is not easy because the pairs observed do not follow a single line, but rather cloud of points around an ideal definition of it. This is the reason why the concept of the power curve has been extended in this paper to a normal power generation area for a period of time taken as reference for later comparisons. This area has to cover the most part of the data observed in the period considered as reference of performance. Once a normal power generation area is defined, it can be used to detect possible deviations in future observations. The paper includes some examples of application to four wind turbines where some abnormal deviations of performance were detected. Also, an analysis is included of other measured variables that could feed a complementary view about the results observed in the study carried out.","PeriodicalId":287863,"journal":{"name":"2016 IEEE International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127664070","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 South African Renewable Energy Grid Code was then published in 2010 to assist with safe and technical integration of these plants into the South African grid.
