These adjustments combined with seasons that may have less generation of electric energy can make electricity a monetary concern, especially for industrial customers. With the increase of price in electricity bills, the management of energy is a fundamental tool to achieve energy efficiency and reduce costs while maintaining the same production rate. In Brazil the energy efficiency policy is rarely adopted, not having a significant amount of systems that can provide such service effectively and at a low cost. This paper proposes the development of a low-cost prototype for monitoring the consumption of electricity in real-time using communication with electronic meters of power distribution companies (ISO 50001) and a web platform that can process and display the data. Making a comparative analysis with the daily collected data from the prototype, it's possible to find patterns of power consumption, high demand moments and abnormal use of energy. The prototype was able to provide important data that can be used to make rational choices regarding on how to optimize the consumption of energy and achieve energy efficiency, making it a cheap and reliable energy management system.","PeriodicalId":223855,"journal":{"name":"2019 IEEE CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130260729","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}

Several research works in the field of computer security have identified serious security and privacy risks in the WIMD that could compromise the implant and even the health of the patient transporting it. This article analyzes the most relevant protection mechanisms proposed up to now and examines the main mechanisms of patient safety. On the one hand, security proposals must take into account the inherent limitations of these small and deployed devices. On the other hand, the proposed solutions must achieve an adequate balance between patient safety and the level of safety offered.","PeriodicalId":223855,"journal":{"name":"2019 IEEE CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON)","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128077269","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 this paper we present a communication-based fault location methodology, which uses directional fault passage indicators (FPIs) communicated with a control center. Through the information received by the FPIs, the location of faults and the isolation of the affected areas are carried out. In addition, it performs the restoration of service in healthy lines, if possible, by means of a reconfiguration of the topology of the microgrid through sectionalizers.","PeriodicalId":223855,"journal":{"name":"2019 IEEE CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON)","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134119864","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 cost functions are characterized and simulated to verify the effectiveness of the working method and the claims made in this investigation. It was found that modelbased predictive control is a powerful alternative when there are multiple objectives, which can be included efficiently within a cost function.

In order to overcome this effect, the additional filter elements are added in the Luo-converter to eliminate the output ripples and effectively enhance the output voltage level. The output stage of the Luo converter is comprised of an inductor and capacitor so it naturally acts as filter. The output stage stores and delivers energy to the load and smoothens the output voltage to produce a constant output voltage. The Luo Converter acts as both buck and boost converter by varying the duty cycle. Thus this Luo Converter is used for the proposed BLDC Motor Drive. The Sliding Mode Controller is used to make the speed of the System constant in a small amount of time.","PeriodicalId":223855,"journal":{"name":"2019 IEEE CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124723309","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}
