Abstract(s)
A racionalização do consumo de energia elétrica é um tema que assume uma importância crescente nos dias de hoje. O elevado consumo de energia, principalmente a nível comercial/industrial, tem motivado o aparecimento de questões políticas, económico-sociais e ambientais que visam a sensibilização dos consumidores para a gestão eficiente dos seus recursos. Neste sentido, as empresas e instituições têm demonstrado interesse em encontrar soluções de gestão nas suas instalações elétricas que permitam a monitorização de indicadores e a previsão de falhas cuja ocorrência acarreta elevados custos de reparação/substituição, de paragem de produção, entre outros.
O estudo aqui apresentado surge no âmbito de um projeto académico, cuja finalidade se prende com a implementação de um sistema de monitorização da qualidade e consumo de energia elétrica no Instituto Superior de Engenharia do Porto (ISEP). Baseado numa rede de dispositivos analisadores de parâmetros de energia elétrica, estes equipamentos de medição dispõem de software próprio, o GridVis, que permite o acesso remoto, através de uma rede Ethernet, aos parâmetros de energia (grandezas físicas elétricas). O sistema desenvolvido é capaz de identificar parâmetros de consumo de energia anómalos e emitir alertas, pré-programados em linguagem C++ e diagrama de blocos. Permite, por exemplo, detetar um consumo instantâneo excessivo de energia e alertar a sua ocorrência.
As páginas de acesso aos parâmetros medidos por cada dispositivo são acessíveis através de uma interface gráfica desenvolvida em Adobe Flash que inclui, de uma forma simples e organizada, a informação relativa à distribuição dos dispositivos de medição.
Num contexto de expansão deste projeto para outros edifícios do ISEP, a solução desenvolvida encontra-se preparada para ser adaptada em qualquer local, desde que reúna certos requisitos.
The rationalization of energy consumption has increased its importance these days. The energy consumption rate has grown during the last decades, which has led to the appearance and reinforcement of social and environmental concerns about the intelligent and sustainable management of energy resources among consumers. To fulfil these requests, corporations and institutions have been interested in methods that allow to efficiently supervising the main energy indicators and to accurately predict failures that usually lead to high operating costs of repairing or substitution. This study aims to implement a monitoring system for power quality of electric energy consumption to consumer devices in Instituto Superior de Engenharia do Porto (ISEP). This system is based on a network of energy analysers that measure several parameters of electric energy. These instruments are provided with their own software (GridVis), which allows, via Ethernet, to access remotely to the variables and energy parameters being measured. Moreover, the system is capable of identifying abnormal consumption parameters and send automatized alerts, previously developed by using the C++ programming language and block diagrams. As an example, the system allows to detect excessive energy consumptions and send instant notifications to warn those occurrences. A graphical user interface application was developed to access the pages of the devices where the parameters being measured are shown. This application is conceived to retrieve the information related to the allocation of energy analysers in a simple and organized way. The developed system provides the requirements needed in case of expansion to the remaining buildings of ISEP.
