Implementation of 288 KWP Photovoltaic Solar System On-Grid in a Manaus Industrial Polo Company

The rational use of electricity is practically mandatory, due to the current moment in which the country crosses, mainly due to the reduced reservoir levels of the hydroelectric plants, and where there are high costs in the production of its fuel inputs. fossil fuels, and recent tariff adjustments that the government has been approving year after year, making conventional energy increasingly expensive in the country. Companies and households focus on looking for ways to dodge electricity inflation through clean and renewable energy sources, as is the case here, of photovoltaic solar energy. Aiming to supply about 70% of the electricity bill of a Company of the Manaus-AM Industrial Pole, this work proposes a 288 KWp photovoltaic solar system, consisting of 900 330 W photovoltaic panels, accompanied by 10 Inverters. 30 KW each, connected to the Amazonas Energia Distribution Network, featuring an On-grid solar system, and becoming the largest executed solar energy project in the Amazon and Northern Brazil. The implementation of the system seeks to make feasible and solve the high cost of the electric bill with the application of a solar system, and analyze its investment, financial return and clean energy generation for the next 25 years

The study had bibliographic research and data comparison, providing references to diagnose the root of the problem presented in the production process related to the aesthetic quality of the finished product (Lithium Ion battery for mobile). Using the 5S program to implement and guide employees in new work habits, ensuring product and process quality, avoiding waste and enabling continuous improvement

Prototype Development Open Source Platform-Based Electricity Meter with Minimum Rate of Change According to Module Five of the Electricity Distribution Procedure in the Brazilian National Electrical System (PRODIST)

The article proposes the development of a low-cost, well-performing open source residential energy consumption demand meter compared to commercial meters in order to achieve accurate results and remain within the limits determined by technical standards, with the objective of measuring real and instant energy consumption through microcontroller and current sensor. The prototype has the ability to provide energy consumption data for a low voltage residential load or wiring to obtain the final amount of energy consumption Data is collected in stages by collecting current and voltage,  the microcontroller receives analog stimuli from sensors, as voltage and current samples are processed to calculate power, current and voltage. The use of the device leads the consumer to clarify the instantaneous energy consumption per installed component and it is possible to compare the cost benefit in relation to the energy consumption, providing consumers the follow up and a detailed view of its consumption, leading to efficient and sustainable use, enabling the improvement of the quality of energy supply to equipment connected to the distribution system

Proposed Use of Photovoltaic Energy in a Traffic Light System

The implementation of the replacement of a conventional semaphore system with one powered by photovoltaic energy in the city of Manaus. Nowadays, energy generation has been approached as one of the vitally important issues. The increasing demand for energy in the country and the importation of new technologies conditioned to the use of electricity have been demanding better energy planning, given the energy potential of the northern region for the implementation of a photovoltaic system directed to the semaphore system. In this scenario it is important to identify the impacts caused by the replacement of incandescent lamps with LED technology with the consequent reduction of energy consumption and maintenance costs. In addition, the purpose of this study is the inclusion of photovoltaic panels in traffic lights, seeking a sustainable form of operation. It is noteworthy that the process of analyzing the results of this project was based on measurements made before and after the replacement of the equipment, thus reflecting the actual values ​​of electricity consumption and active power demand

Educational approach for fault detection in Internal Combustion Engines with Matlab Toolbox Fuzzy Logic

Fuzzy logic is the logic defined from the theory of fuzzy sets. It differs from the crisp logic (traditional) in their characteristics and their details. In textbooks on fuzzy inference systems, exemplified superficially implementation creating doubts among computer science students. Traditionally, teachers teach IC with the use of conceptual models. This model was to serve specified parameters computing courses, allowing students to study and development of computational models using Matlab Fuzzy Logic Toolbox (MFLT) for fault detection in engines. This paper proposes an academic learning model based on fuzzy inference and modeling to detect incipient faults in components of internal combustion engines

Uso da palhada da cana-de-açúcar na geração de etanol 2° geração versus sua contribuição nutricional para o solo no ambiente cerrado

Com a colheita da cana crua, sem o uso da queima, fica depositado ao solo uma grande quantidade de material vegetal, que agrega benefícios ao solo. Em contrapartida, há uma grande demanda pela retirada parcial ou integral dessa palha devido seu grande potencial energético e calorífico, o que pode aumentar significativamente a produção da bioenergia e do etanol de segunda geração. Objetivou-se com este trabalho avaliar a taxa de decomposição da palha de cana de açúcar, a economia gerada pelo retorno dos nutrientes ao solo pela mineralização, e seu potencial de geração de etanol de 2° geração (E2G). O potencial econômico pela produção de etanol foi avaliado pelos dados comparativos de 3 quantidades de palhada deixada sobre o solo no decorrer de uma safra correlacionando com tabelas de mineralização disponíveis na literatura e confrontando com o potencial de produzir E2G. Para este estudo, considerou-se três diferentes cenários para analisar o retorno econômico da manutenção ou retirada da palhada. Para determinação das taxas de decomposição foram utilizadas três diferentes quantidades de palha (10,6, 16 e 32 Mg.ha-1). Observou-se que, em média, a palhada de cana-de-açúcar mantida sobre o solo apresenta taxa de decomposição de 13% da massa seca. Observou-se ainda, que quando mantida, há uma economia em relação a aplicação de fertilizantes para reposição de nutrientes após um ciclo de cultivo. Já quando a palhada é retirada e utilizada para produção de E2G, o retorno econômico pode ser até dezessete vezes maior do que quando deixada sobre o solo

Multi-Objective Optimization Techniques to Solve the Economic Emission Load Dispatch Problem Using Various Heuristic and Metaheuristic Algorithms

The main objective of thermoelectric power plants is to meet the power demand with the lowest fuel cost and emission levels of pollutant and greenhouse gas emissions, considering the operational restrictions of the power plant. Optimization techniques have been widely used to solve engineering problems as in this case with the objective of minimizing the cost and the pollution damages. Heuristic and metaheuristic algorithms have been extensively studied and used to successfully solve this multi-objective problem. This chapter, several optimization techniques (simulated annealing, ant lion, dragonfly, NSGA II, and differential evolution) are analyzed and their application to economic-emission load dispatch (EELD) is also discussed. In addition, a comparison of all approaches and its results are offered through a case study
