In this context, reliable and quality information is needed to support decision-making on environmental risk issues, such as land use change, reduced fertilizer use time, the choice of those with fewer trace elements such as copper etc. For this reason, in very important software simulation that allows to estimate the effect of fertilizers on the concentration of traces in the future. Currently, it is possible to use Hydrus 1-D, which is a free access and internationally used software, which however is difficult to handle data and of high mathematical complexity. This research proposes to alternatively use a model implemented in Matlab, which performs functions equivalent to Hydrus 1-D, but with a soil database with a single screen input. As a result of the work, results and conclusions are delivered, which validate the experimental data and show the advantages of using this new software.","PeriodicalId":223855,"journal":{"name":"2019 IEEE CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON)","volume":"115 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":"121518046","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}

Among the various air pollutants, PM2.5 (particulate material with diameter less than 2.5 micrometers) is relevant because high concentrations in the air can trigger respiratory, vascular or even lung cancer problems to people that live in contamined areas. Currently, the prediction of concentration of this material in Santiago de Chile is typically based on statistical methods or classic neural networks. In this work, we propose a model for the prediction of PM2.5 concentration and its critical events in Santiago de Chile through the use of recurring LSTM and GRU networks. In particular, data from the air quality monitoring stations located in different parts of the city of Santiago is used to predict the level of pollution by hours. The work describes the experiments carried out, with particular emphasis to the preprocessing of the data for its importance in the identification of the model. The obtained experimental results show that the performance of the GRU network slightly exceeds the LSTM network, reaching a coefficient of determination greater than 0.78 in independent set of testing data, while the threshold prediction in both networks exceeds 0.87 of R2 in the same testing set. As future work, we intend extend the proposed models to a spatial prediction throughout the city of Santiago.","PeriodicalId":223855,"journal":{"name":"2019 IEEE CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON)","volume":"110 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":"127989007","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, a multi-objective optimization model is developed, which according to technical, economic and environmental requirements, allows determining the configuration of the long-term generator park in the electrical system and it also allows assessing the impact on the emissions of greenhouse gases. The analysis of alternative expansion of the generator park allows determining, for each different scenario, the annual operation hours of each generating technology, the investment and operation costs along with the level of CO2 emissions. The assessment horizon of this study was established by the year 2030. The main conclusions indicate that in order to achieve an effective reduction of global emissions, the incorporation into the energy matrix of low GHG emission technologies such as CCS and nuclear energy should be considered, insofar as they are cost effective and socially and environmentally compatible. In addition, the incorporation of the CCS allows that the coal increases its competitiveness compared with other technologies because in a LNG restriction scenario it is required a high availability and participation of coal power plants.","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":"133110882","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 compares the performance of the recommended functions by ONS with the negative sequence and REF functions, in order to demonstrate if there is any sensitivity and reliability gain. In order to do so, the following protection functions were implemented: phase (87T) and negative-sequence differential (87Q) as well as restricted earth fault differential protection (87REF); overcurrent protection (50/51) and restricted earth fault directional protection (67REF). The evaluation of these functions was by parametric sensitivity analyzes (PSAs). The obtained results reveal the performance of these functions for transformer internal short circuits, considering the influence of the following parameters: percentage of short-circuited turns, sources strength and conditions of system loading.","PeriodicalId":223855,"journal":{"name":"2019 IEEE CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON)","volume":"11 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":"121369929","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}
