Abstract
"DETERMINAçãO DE UM LIMITE OPERACIONAL DE UMA LINHA DE TRANSMISSãO DE ENERGIA". Em um método, o programa de computador e sistema para determinação de um limite operacional de uma linha de transmissão de energia informação de fasor de corrente com selo de tempo e informação de fasor de voltagem para uma primeira extremidade e uma segunda extremidade da linha são determinadas; uma resistência óhmica da linha é computada a partir da informação de fasor; e uma temperatura média de linha é computada a partir da resistência óhmica. Isso permite a determinação da temperatura média de linha sem sensores de temperatura dedicados. A temperatura média de linha representa a temperatura média real e depende muito das considerações referentes aos parâmetros de linha.
