Abstract

1 / 1 resumo “sistema configurado para indexar dados, e, mã‰todo para indexar dados” a descriã§ã£o presente relaciona-se a procurar formas de onda de sistema de energia elã©trica. descritos aqui sã£o vã¡rios sistemas e mã©todos para melhorar desempenho de procura indexando formas de onda de sistema de energia elã©trica usando atributos de forma de onda tais como frequãªncia, amplitude, ã¢ngulo, taxa de mudanã§a, e similar. de acordo com algumas concretizaã§ãµes, mãºltiplos ã­ndices podem ser usados juntos para achar informaã§ã£o de interesse. um sinal de referãªncia pode ser utilizado de acordo com algumas concretizaã§ãµes. normalizar uma pluralidade de formas de onda usando um sinal de referãªncia pode facilitar o uso de um ã­ndice para comparar duas formas de onda arbitrã¡rias. esta descriã§ã£o tambã©m relaciona-se a detectar e indexar condiã§ãµes de ilhamento em um sistema de energia elã©trica. vã¡rias concretizaã§ãµes podem utilizar informaã§ã£o relativa a condiã§ãµes de ilhamento com relaã§ã£o a operaã§ãµes de procura.
