Estudo da comunicação de um compensador série para rede de distribuição com o centro de controle utilizando tecnologia GPRS /Maldonado, Esleyra. January 2013 (has links)
Orientador: Dionízio Paschoareli Júnior / Banca: Ailton Akira Shinoda / Banca: Gilson Paulillo / Resumo: Atualmente, a tecnologia da compensação que utiliza controladores eletrônicos para a flexibilização dos sistemas (controladores FACTS) provê recursos aos sistemas de transmissão de energia elétrica que permitem o controle dinâmico do fluxo de energia desde a geração até o consumo. Para que se torne factível o uso de FACTS no sistema de distribuição, faz-se necessária a implantação de um sistema de comunicação para o monitoramento em tempo real de toda grade de energia até o centro de controle. Com o controle dinâmico e o monitoramento dos diversos equipamentos distribuídos no sistema de energia, tem-se o conceito das Redes Inteligentes ou Smart Grids (SG). Através deste conceito, as tecnologias de informação e comunicação (TIC) terão um papel relevante em todas as fases do ciclo de geração, transporte, comercialização e consumo. A realidade da SG deve transformar o sistema elétrico. Nesse sentido, este trabalho propõe, através da análise teórica, uma solução para comunicação entre o compensador série controlado a tiristores para rede de distribuição (D-TCSC), localizado em uma rede de distribuição na zona rural, com o centro de controle, localizado a centenas de quilômetros de distância. A tecnologia sugerida, de acordo com as características do estudo de caso, foi a GPRS. A sugestão foi feita analisando a relação entre a quantidade de dados a ser transmitida e o tempo de transmissão. Os resultados das análises mostram que a utilização de a tecnologia GPRS, para efetuar a comunicação em aplicações de teleproteção, é factível. Entretanto, para alcançar melhor desempenho, sugere-se a utilização das tecnologias 3G e 4G, quando estas oferecerem cobertura de sinal para ambientes remotos / Abstract: Nowadays, FACTS controllers are very important for allowing dynamic control of power flow from generation to consumption. The use of FACTS controllers in distribution systems has become more feasible with the implementation of communication system for real-time monitoring. The dynamic control and monitoring of several equipment in distributed power system has arisen the Smart Grids concept. Through this concept, the information and communication technologies (ICT) have important role in all stages of generation, transportation, marketing and consumption. The SG shall transform the electrical system. This work proposes, through theoretical analysis, the communication between a thyristorcontrolled series compensator, located in a distribution network in the countryside, with the control center, located several hundred kilometers away. The suggested technology, according to the characteristics of the study case, was the GPRS. The suggestion was based on the ratio among the distance, the amount of data to be transmitted and the transmission time. The analysis results show that the use of the GPRS-technology to provide communication in a SG is suitable / Mestre
