Resumo(s)
A RNT (Rede Nacional de Transporte) é constituída por um conjunto de linhas que fazem o transporte
de energia desde os centros produtores até aos centros de distribuição. O operador da RNT definiu
valores de capacidade sazonais para estas linhas utilizando uma metodologia conservadora uma vez que
utiliza condições meteorológicas conservadoras para definir os valores de capacidade.
Ao longo deste trabalho irá ser abordado o conceito de DLR (Dynamic Line Rating – Análise Dinâmica
de Linhas) que, através de modelação numérica de variáveis atmosféricas e parâmetros físicos das linhas,
estima a capacidade real das mesmas. Este modelo vai ser aplicado nas linhas de forma a calcular a real
capacidade das mesmas e a estabelecer uma comparação entre a capacidade pré-estabelecida pelo
operador da RNT e a capacidade obtida através do DLR.
Também irá ser feita uma análise ao vento localizado na zona do Vale Cobrão uma vez que no local
existe um Parque Eólico instalado. Esta análise visa a uma posterior aplicação do conceito de DLR com
o intuito de se aceder à capacidade das linhas em momentos de alta produção vinda do Parque Eólico.
The national transport grid its composed by an amount of lines that are responsible for the transportation of the energy since the production centre until the distribution point. The TSO (Transport System Operator) has standard values for the seasonal capacity of this lines that were pre-defined using a conservative methodology that assumes conservative meteorological variables to define the line capacity. In this work it will be use the DLR (Dynamic Line Rating) concept by using numeric modelation of atmospheric variables and physical parameters of the lines in order to estimate the real capacity of them. This model will be applied in order to calculate the real capacity of the lines and to stablish a comparation between the pre-established capacity from the TSO and the capacity obtained from the DLR It will be do wind analysis of the wind located in the Vale Cobrão because is a site where a wind central is installed. This analysis was made in order to do a future application of the DLR concept with the propose of estimate the capacity of the lines that connect the wind turbine to the grid in moments that there is a high production from the wind park.
