Abstract(s)
Nos tempos atuais as empresas que atuam no ramo dos sistemas elétricos de energias enfrentam desafios cada vez mais exigentes, dado o enquadramento normativo a que estão sujeitas por parte da entidade reguladora dos serviços energéticos. No caso do Arquipélago dos Açores, o normativo relativo ao regulamento da qualidade de serviço entrou em vigor em 2006, trazendo à EDA,S.A. (Eletricidade dos Açores), entidade responsável pelo transporte e distribuição de energia na região, novas exigências para adequados níveis de eficiência e de garantias aos clientes, no que respeita à qualidade de serviço que lhes é prestado.
No âmbito deste trabalho, é efetuado o estudo do trânsito de potência sobre a rede distribuição 15 kV da ilha Graciosa. Para tal, é realizada a modelização da rede no software de rede elétricas porwerworld 8.0. e são idealizados um conjunto de cenários de exploração da rede, que visam simular situações reais que ocorrem na exploração diária da rede de distribuição da ilha. Nas simulações a efetuar consideram-se dois cenários com perfil de carga distintos, um referente à ponta máxima, e outro referente ao vazio mínimo, verificados no ano de 2014. Quanto ao modo de exploração da rede nos cenários a simular, é contemplado o modo de exploração normalmente operado pela empresa gestora, bem como diversas reconfigurações sobre o modo de exploração normalmente operado, realizadas através da abertura e fecho dos aparelhos de corte constituintes da rede. Em todos os cenários simulados, é realizado um estudo relativamente à potência de perdas do sistema, ao perfil da tensão nos diversos postos de transformação, e ao congestionamento de energia verificado nas linhas de distribuição da rede.
Currently the power eletric system utilities are facing more demanding challenges, due to the normative concept instituted by the energetic services regulator entity. In regard to the Azores archipelago, the normative about service quality regulation came into rule in 2006, bringing to EDA,S.A. (Eletricidade dos Açores), entity responsible by the power transportation and distribution in the region, new requirements to suitable efficiency level and client guarantees, in order to respect the quality of service supplied to them. In the scope of this report, it is studied the power flow on Graciosa distribution network 15 kV. For that purpose, it is executed the distribution network modeling in the eletric network software powerworld 8.0. and it is idealized several operation network scenarios, which aim to simulate real situations that take place in the daily distribution network exploration. In the simulations it is considered two distinct profile load, peak and off-peak load, observed in 2014. Regarding the way of the network operation, it is considered the way of exploration normally operated by the company manager as well as several reconfigurations over the way normally opereted, by opening sectionalizing (normally closed) and closing tie (normally opened) switches of the network. In all the scenarios simulated, it is studied the active losses in the system, the buses voltage magnitude and the distribution line load percentage.
