A new harmonic data distribution window was developed, through the collection of data from the distribution network, in a medium voltage substation of level 13.8 kV. The objective of this article is to obtain a study on the energy for the consumer units (UCs), for a minimum period of 7 consecutive days according to the PRODIST, electrical system. The harmonics are not as ha rmful for firms as for power distribution company. A technique developed of this article is a linear regression technique, which is a construction of parametric models and a mathematical analysis. This is an article published and applied in the practice of case studies of harmonic analysis of electric energy distribution systems through linear regression analysis, obtaining great results in the study, thus validating an applied technique in harmonic analysis of electric power distribution systems.

Considering recent cases of mobile device battery incidents widely reported in the news and the internet, more and more companies are looking to develop not only safer and more reliable products, but also robust and automated manufacturing processes, seeking greater reliability and efficiency. Thus, the purpose of this research is to model a mobile phone battery test automation system using the Petri Nets (PN) graph and mathematics tool to automate the dipole alignment, voltage test and internal resistance, anode and cathode battery terminal cut, visual inspection of these and battery thickness selection in a mobile phone battery production line of a company in the Industrial Pole of Manaus (PIM). The Visual Object Net ++ v2.7a software was used for PN modeling and the present research is structured in detailed description of the automatic system components, flowchart, modeling and PN analysis. Considering this as a Discrete Event System (DES), the PN showed that it is fu lly possible to model the Automatic Testing System for Mobile Phone Battery. It was also demonstrated that the PN analysis by the mark enumeration method, through the coverage tree building and accessible markings graphs that the system has good properties of Reachability, Liveness and Boundedness, being fundamental in PN. It was also possible to verify that using this tool it is possible to obtain a high level of understanding of real progress and evolution of the system through the dynamic visualization of graphs related to the DES.

Modeling, as a means of analysis of safety systems, as well as industrial processes and related purposes, meets the demand for suitable methods. The present work aims to evaluate an adherence of the concepts of modeling and Petri nets applied to the logic and interlock strategies of a Fire Fighting System (FFS). For this purpose, a real installation was used to acquire the information, which was an Oil & Gas Waterway Terminal, located in the municipality of Coari in the State of Amazonas, Brazil, which receives, stores and disposes of oil and liquefied petroleum gas (LPG). The analysis models and the interlocking strategies are validated with the use of the Petri nets, where are the patterns of systems to discrete events, through a method of analysis in which all the paths and states that the modeled system are simulated It can obtain, to allow from this model to study and evaluate possibilities of improvement of the system.

One of the main sources of petroleum products beneath ground in Brazil it is obtained from the Amazon forest. Where the main problem faced during the flow of this product is to maintain the constant pressure and flow at the highest possible level. In this work, the parameters such as the pressure and flow of a pipeline are constantly maintained through the implementation of control valves, depending on the difference of pressure, flow and temperature in the pipeline. PLC Aspectos de controle PID baseado em CLP Aplicado ao controle de duto petrolífero localizado em Coari-Amazonas RESUMO Uma das principais fontes de produtos petrolíferos em terra no Brasil é obtido a partir da floresta amazônica. Aqui, o principal problema enfrentado durante o escoamento deste produto é manter a pressão constante e vazão no maior patamar possível. Neste trabalho, os parâmetros tais como a pressão e vazão de um oleoduto são mantidos constantemente através da implementação de válvulas de controle, dependendo da diferença de pressão, vazão e temperatura no duto. CLP (Controlador Lógico Programável) é usado para regular automaticamente a vazão e a pressão durante o transporte do petróleo através do controle da porcentagem de abertura das válvulas de controle. O ponto de ajuste desejável para a pressão e vazão são obtidos através da implementação de um controlador adequado que regula as variáveis operacionais da tubulação. Para isso, um controlador PID baseado em PLC é desenvolvido e suas respostas em malha aberta são identificadas. Os estudos de simulação são realizados na plataforma MATLAB/SIMULINK para garantir o desempenho do controlador. A Regulação do controlador é feito por ZN (Ziegler e Nicholas) PID e os resultados provam que proporciona um desempenho consistente com relação aos requisitos operacionais da unidade.Palavras Chaves: Controle PID, Oleoduto, Pressão. I. INTRODUÇÃOPetróleo (literalmente, "óleo de rocha") é uma substância que se formou sob a superfície da terra ao longo dos anos. Os restos de plantas e animais antigos foram enterrados e comprimidos sob milhares de metros de areia, lama e rocha. Os materiais orgânicos, em certas condições geológicas, foram transformados por pressão de
