The system provides a pattern of variables that exhibit abnormal behavior in the presence of a fault. The patterns are formed with the detection of the abnormal behavior of the variables during a time window in which the failure manifests itself. This paper presents the application of machine learning techniques for the identification of faults in wind turbines after the diagnostic system. The training and validation data were obtained from the simulation of six different faults in the wind turbine using the Mexican Wind Machine (MEM) designed at the National Institute of Electricity and Clean Energy (INEEL). The diagnostic system was applied, profiles of abnormal behavior were generated and experiments were carried out for the multiclass classification of fault patterns using the \"Random Forest\" algorithm. Finally, the algorithm performance was evaluated using accuracy and precision metrics achieving 91% in the classification of patterns to identify the root failure.","PeriodicalId":329432,"journal":{"name":"Revista de Energías Renovables","volume":"2 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115689345","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 addition, all these systems are sensitive to operation and maintenance costs. This article proposes the use of commercial Fresnel lenses to improve the efficiency of photovoltaic modules, in conjunction with a fuzzy intelligent controlled solar tracking system with two-axis and a novel low-cost robotic cleaning system. The basic idea is that this system optimizes the production of electricity in an economically and technologically simple way. The technology of Arduino microcontrollers and fuzzy logic for control, as well as the geometry of Fresnel lenses, will be used to concentrate solar energy in a small area, not to mention that these optical devices have a low weight. The accumulated effect of energy production will be improved by a novel low cost robotic cleaning system. The alignment and perpendicularity of the impact of solar energy on photovoltaic cells must be maintained as much as possible and the performance of this system must be compared with other more expensive and technologically more complex commercial systems.","PeriodicalId":329432,"journal":{"name":"Revista de Energías Renovables","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134531461","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 research was conducted under a mixed approach, using an experimental, systematic, descriptive, explanatory, correlational, empirical and in a field context, the variables considered for the development of the research are the amounts of hydrogen, diesel, oxygen, time and concentration of the mixture for the experiments. The prototype presented controlled operating conditions depending on the delivered hydrogen flow to obtain the operating curves of the diesel engine (pressure-volume, temperature-entropy), setting the necessary concentration of the mixture for optimum performance for the internal combustion cycle.

The solar energy is directly used by green plants and other photosynthetic organisms, capable of capturing solar energy, transforming it into chemical energy and storing it. This natural process is called photosynthesis and consists of converting solar energy, water and carbon dioxide into carbohydrates and oxygen that act as nutrients for plants. The photosynthesis process technology is based on a biological generator that obtains electricity from the decomposition of organic substances extracted naturally from plants. It do it by releasing electrons and H2O in the process, without causing damage to any living organism.
