Instead of using ferrite to insert a magnetic field on the device, accountable to generate the non-reciprocity phenomenon on the ferrite circulator explained by the Larmor precession, the same behavior are achieved using a proposed Π topology circuit with modulated variable capacitance. Four different simulations are presented in order to explore the results variation according to the parameters changing. The simulations are done using the Advanced Design System software and the operation frequency are 902-928 MHz with central frequency at 915 MHz.","PeriodicalId":148750,"journal":{"name":"2018 Workshop on Communication Networks and Power Systems (WCNPS)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128357221","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}

Da Costa, Marcos T. de Oliveira","doi":"10.1109/WCNPS.2018.8604345","DOIUrl":"https://doi.org/10.1109/WCNPS.2018.8604345","url":null,"abstract":"Recently, the number of accidents and incidents involving remotely piloted aircraft (RPA) have dramatically increased. Therefore, the development of a complete software and hardware system based on antenna arrays and direction of arrival (DoA) estimation for the localization of intruding RPA has attracted the attention of researchers and engineers. DoA estimation can be achieved via relative phase between antennas in an antenna array or via received signal strength (RSS) estimation of an array of directional antennas. Previous works on DoA estimation via received signal strength (RSS) used platonic solid geometry associated with the multiple signal classification (MUSIC) algorithm. In this paper, we propose a novel DoA estimation algorithm for the localization of drones exploiting their incoming NTSC video signal. Next we validate our algorithm by using an AD-FMCOMMS5-EBZ software defined radio (SDR) platform with a Yagi-Uda antenna array in a measurement campaign. The results from the measurement campaign show that from the 19 different measured DoAs from −90° to 90° with steps of 10°, we obtained a good measurement for 14 estimates, including the end-fire positions, which are critical in traditional omnidirectional antenna array based solutions.","PeriodicalId":148750,"journal":{"name":"2018 Workshop on Communication Networks and Power Systems (WCNPS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129225121","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, to verify if the relay-based protection systems are capable of identifying electrical faults in a distribution system with a great number of distributed generation (DG) of the doubly-fed induction generator (DFIG) type is essential. Notwithstanding, the wavelet-based directional overcurrent protection at the 30 bus bar IEEE distribution system with different percentage of DFIG-based DG's insertion on grid is analyzed. Simulated results using Matlab/Simulink are presented to verify if the protection is capable to detect backward and forward faults at this scenario. Finally, considering the overall system performance, the protection assessed is concluded being reliable.","PeriodicalId":148750,"journal":{"name":"2018 Workshop on Communication Networks and Power Systems (WCNPS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121515263","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}
