Abstract

Detecção de efeito ilha em grades de energia. Um método para detectar uma condição de efeito ilha em uma grade elétrica apresentando uma tensão na linha de energia inclui monitorar um sinal detectável (306) diferente da tensão na linha de energia na estação de geração (310) de energia, sobrepor o sinal detectável na tensão da linha de energia em um ponto da grade (308) fora da estação de geração de energia, e chavear a estação de geração de energia de um modo de operação ligado à grade para um modo de operação em efeito ilha quando o sinal, ao qual o detector (312) responde, é determinado como estando ausente.
