Instalação elétrica para o hospital naval papa francisco: desenvolvimento do pr...
Sousa Junior, Elder Alves de; Silva, Francisco Jeandson Rodrigues da; Costa, Douglas Aurélio Carvalho; Moura, Ailson Pereira deThe present work aims at the use of electrical installations in naval environments together with the hospital environment at Barco Hospital Papa Francisco (BHPF). The work presents the development of the electrical installation at BHPF, showing the technical standards applied to the electrical sector of vessels and hospitals. The analysis of electrical loads on the ship is carried out in order to have the insta...
Análise de perdas técnicas em sistemas de distribuição
Silva, Francisco Jeandson Rodrigues da; Moura, Ailson Pereira de; Moura, Adriano Aron Freitas de; Costa, Douglas Aurélio Carvalho; Vieira, Obed LeiteTraditionally, the analysis of technical losses in distribution systems is done using a load flow program. However, the application of a methodology using measurement and simulation data together was not done. This paper uses the average demand of a representative day, measured on the secondary of the 69 / 13.8 kV transformers of an Enel Distribuição Ceará regional electric system Sobral feeder, to calculate th...
Sistema de compensação de energia elétrica com geração distribuída: propostas p...
Sousa Junior, Elder Alves de; Sena, Lucas Beserra de; Oliveira, Luan Ney de Carvalho; Santos Neto, João Cordeiro; Matos, João Paulo Mathias deA geração hidroelétrica é a principal fonte de geração de eletricidade no Brasil, com uma participação de 65,2% na matriz de energia elétrica do país. Com o objetivo de descentralizar e diversificar a matriz brasileira, afim de tornar o sistema elétrico nacional mais confiável. Outras fontes de energia elétrica aumentaram a participação na matriz brasileira, principalmente após a criação da Resolução Normativa ...
Uso de testes de hipóteses para verificar a relação entre chuvas e interrupções...
Vieira, Obed Leite; Castelo, Camilo Martins; Silva, Francisco Jeandson Rodrigues da; Costa, Douglas Aurélio Carvalho; Soares, Fellipe SoutoSeveral climatic events are the causes of interruptions in the energy supply in the electricity distribution system. Among them, rains are empirically considered direct causes of the interruption. To statistically verify the existence of a relationship between the increase in the number of interruptions and rain occurrence, the hypothesis test theory is used. A comparison of the difference in means between two ...
A importância do Laboratório de Energias Alternativas da Universidade Federal d...
Silva, Francisco Jeandson Rodrigues da; Costa, Douglas Aurélio Carvalho; Vieira, Obed Leite; Soares, Fellipe Souto; Carvalho, Paulo Cesar Marques deThe present paper aims to verify the students' opinion about the importance of the Laboratory of Alternative Energies (LEA) for the development of researches and academic formation of the engineering courses of the Federal University of Ceará. In a way, there is a considerable gap between the absorption of scientific knowledge through theoretical and experimental lectures. Thus, the purpose of the LEA is to red...
Percepção dos discentes sobre o uso do Software Pythontm na aplicação do Método...
Oliveira, Edneide de Matos; Rocha, Maria Valderez Ponte; Silva, Francisco Jeandson Rodrigues daThe present study presented the use of the Euler method for the resolution of Ordinary Differential Equations (ODE) by undergraduate students of the course in Mathematical and Computational Methods Applied to Chemical Engineering, of Chemical Engineering from Federal University of Ceará (UFC) being made by two researches: field and bibliographical. The field research was developed with the students who study or...
Aplicação do analisador de energia no combate as perdas comerciais em média tensão
Silva, Francisco Jeandson Rodrigues da; Vieira, Obed Leite; Costa, Douglas Aurélio CarvalhoBrazilian energy distribution companies have problems with financial losses: fraud, diversion of energy, theft of materials and equipment, etc. These financial losses (or commercial losses) are difficult to measure quantitatively, causing losses to the concessionaires of energy impacting on the quality of their supply. This work comprises in a study of the commercial losses of energy in the Brazilian distributi...

Oliveira, Edneide de Matos; Alencar, Cely Martins Santos de; Silva Júnior, Ivanildo José da; Silva, Francisco Jeandson Rodrigues daThe mentioned study approached the use of active methodologies in a class of third semester from the course Chemical Engineering, Universidade Federal do Ceará (UFC) applied by the professor of Principles of Chemical Processes (PCP). To perform the study, two researches were conducted: bibliographic and field. The first was conducted utilizing various sources, among them: books, magazines, internet articles, et...
Algoritmo genético para estimação do potencial fotovoltaico de uma geração dist...
Costa, Douglas Aurélio Carvalho; Braga, Arthur Plínio de Souza; Carvalho, Paulo Cesar Marques de; Soares, Fellipe SoutoIn this paper, a genetic algorithm (GA) is used to estimate the photovoltaic (PV) potential of a PV distributed generation (DG) with an installed power of 1.5 kWp, connected to the electric power distribution network, in northeastern Brazil, more specifically in Fortaleza, Ceará. Environmental data were collected from global irradiance and ambient temperature in the vicinity of the PV DG, in addition to data of...
Fatores de forma e de escala da distribuição de probabilidade Weibull: um estud...
Silva, Francisco Jeandson Rodrigues da; Costa, Douglas Aurélio Carvalho; Soares, Fellipe Souto; Vieira, Obed Leite; Carvalho, Pollyana Rodrigues deThe purpose of this article is to use a series of wind velocity data () measured in the coast of Ceara state at a height of 100 m during 2016, in order to estimate the parameters of the Weibull probability distribution function, shape factor () and scale factor (), using the following methods: graphical (MG), empirical of Justus (MEJ) and empirical of Lysen (MEL), standard factor of energy (MFPE), maximum like...
