Este livro apresenta o desenvolvimento de um medidor de energia em kWh, baseado em um Wattímetro que permite medir a potência de uma carga através da medição da tensão e corrente que chegam a mesma. Desta forma é estudada a construção de um Wattímetro para corrente contínua para potências de até 700 W. Para isso, mostra a construção de um Voltímetro e Amperímetro baseado no PIC18F1220 programado em C, com base no compilador C18 e ambiente MPLAB X. Após o cálculo da potência é feito o produto com uma base de tempo de modo a encontrar a energia consumida ao longo do tempo pela carga conectada a linha.

Este livro apresenta o desenvolvimento de um medidor de energia AC em kWh, baseado em um Wattímetro que permite medir a potência de uma carga através da medição da tensão e corrente que chegam a mesma. Desta forma é estudada a construção de um Wattímetro para corrente alternada para potências de até 7500 W. Para isso, mostra a construção de um Voltímetro e Amperímetro baseado no PIC18F1220 programado em C, com base no compilador XC8 e ambiente MPLAB X. Após o cálculo da potência é feito o produto com uma base de tempo de modo a encontrar a energia consumida ao longo do tempo pela carga conectada a linha.

This authoritative new book focuses on recent developments in the instrumentation for sending voltages and currents. It covers new trends and challenges in the field, such as measurements of biocurrents, the increased speed of the components for data taking, testing of computers and integrated circuits where the measurement of rapid voltage and current variations on a very small geometrical scale is necessary. The first chapter concentrates on recent methods to sense voltages and currents, while the rest of the book investigates the applied side, covering for instance electrical power and energy measurements. The main purpose of this volume is to illustrate commonly employed techniques rather than track the scientific evolution and merits and therefore mainly covers patent literature aimed at industrial applications. It is an exciting addition, justifying the series' claim to cover state-of-the-art developments in both the applied and theoretical fields of sensors and actuators. The measurement of voltages and currents is a common task in the field of electricity and electronics. From a technical point of view it is useful to identify schematically different steps of such a measurement. In a first step a voltage or a current is sensed, intermediate steps such as amplification, transmission and further treatment may follow to yield the result in the final step. Today in most cases microprocessors perform the final steps of such measurements. Analog-to digital converters digitise a voltage that is proportional to the value to be measured and a processor performs further computations and handles the storage and the display of the results. The prerequisite for such measurements are sensors or transducers that respond in a known way to the voltage or current to be measured. The emphasis of this book is put on recent developments of the instrumentation for sensing voltages and currents. Aside from the general trend towards smaller, cheaper and more reliable instrumentation, new demands have arisen. New applications, like measurements of biocurrents, ask for higher sensitivities. Computers and integrated circuits pose new challenges. To exploit the increased speed of the components for data taking, suitable sensors are required. The accuracy that can be achieved depends more than ever on the first step, the acquisition of the raw data. The influence of the measurement process on the results becomes more crucial. Testing of integrated circuits themselves is a completely new application. For such tests one has to measure rapid voltage and current variations on very small geometrical scales. Here, as well as in the traditional high voltage applications, contactless measurements play an important role. The organisation of this book is as follows: In the first chapter different methods to sense voltages and currents are described. For the sake of completeness most commonly used methods are mentioned, we concentrate, however, on those developed recently. The chapters address the subject from the side of different applications in which voltages and currents are sensed. Since the main purpose of this publication is to illustrate commonly employed techniques rather than to track the scientific evolution and merits in particular fields, in general those publications that illustrate a particular measurement principle best have been cited. The citation of a particular reference does therefore not imply that this is the first or most pertinent publication in the respective field.

Esta dissertação apresenta uma metodologia baseada em Algoritmos Genéticos e Teoria dos Conjuntos Fuzzy que determina o número ótimo de medidores de Qualidade de Energia, bem como os pontos onde os mesmos devem ser instalados para monitorar Afundamentos e Elevações de Tensão em redes de transmissão de energia elétrica. A metodologia desenvolvida representa uma ferramenta para diversas áreas de uma empresa de energia elétrica, porque ela indica a melhor maneira para se alocar medidores de Qualidade de Energia, considerando as restrições econômicas a que as empresas estão sujeitas. Além disto, a metodologia também determina a melhor configuração para um sistema de medição para um sistema de potência, quando há barras que devem ser monitoradas e/ou o número de medidores disponíveis é menor que o mínimo necessário para atingir a completa Observabilidade. O trabalho desenvolvido também representa uma importante aplicação dos Algoritmos Genéticos em conjunto com a Teoria dos Conjuntos Fuzzy. Ele define aspectos a serem considerados no problema de monitoração de Qualidade de Energia Elétrica e sugere rapidamente a melhor forma de atender diferentes objetivos e restrições operacionais. A fim de validar o modelo proposto, nesta dissertação, três redes elétricas são avaliadas para determinar o número mínimo de medidores de Qualidade de Energia, bem como a localização onde esses equipamentos deveriam ser instalados.

El objetivo general es el estudio de la problemática del flujo de potencias –tanto para redes monofásicas, como trifásicas– en circuitos distorsionados. Igualmente, se analizaron las técnicas de compensación, y los medidores de potencia y energía, no sólo los utilizados en la actualidad, sino también los que deberían emplearse para la incentivación de la eficiencia en el consumo.
