Abstract

"SISTEMA E MéTODO PARA ALINHAR E SINCRONIZAR DADOS ENTRE FONTES DE DADOS LOCAL E REMOTA E SISTEMA PARA COMUNICAR DADOS ENTRE DOIS RELéS DE SEGURANçA QUE MONITORAM UM SISTEMA DE ENERGIA ELéTRICA". Dados de uma fonte local são primeiramente amostrados (20) a uma taxa de amostragem original que é igual à velocidade de quadros para transmitir os dados para a fonte remota. Os dados de fonte local reamostrados são então retardados (40) pelo tempo de transmissão (36) entre as fontes de dados local e remota. Os dados provenientes do relé remoto que são reamostrados (48) na fonte remota à primeira taxa de amostragem (48) e os dados reamostrados retardados (42) na fonte local são ambos então reamostrados (46) a uma segunda taxa de reamostragem, a uma taxa de amostragem original, para produzir dados alinhados na fonte local.
