Desenvolvimento de uma rede Fieldbus para gerenciamento do sistema de distribuição de energia elétrica

Abstract

This work describes the design and implementation of a Fieldbus dedicated to energy management using a power modem with FSK modulation. The main characteristics of Fieldbus commonly accepted in the market are presented and discussed. Thus, operational aspects of several existent models of power modem are studied. The main aspects of a network dedicated to the energy management using the own energy distribution system as transmission media are defined. Aspects related to the energy network used as transmission media are verified and mathematical models are presented. A power modem module is proposed and implemented, in order to make possible the access to the wanted communication channel. It is presented a design procedure and practical considerations with regard to its operation are verified. A dedicated and flexible communication protocol is developed using the collected information to the management of an energy distribution system. A reliability analysis is accomplished and experimental results are presented.
