Abstract
1 / 1 resumo “dispositivo e mã‰todo para detectar modos de oscilaã‡ãƒo mal amortecidos em um sistema de dispensaã‡ãƒo de energia elã‰trica, e, meio de armazenamento legã�vel por computadorâ€� uma pluralidade de sinais de mediã§ã£o pode ser avaliada para detectar modos de oscilaã§ã£o mal amortecidos em um sistema de dispensaã§ã£o de energia elã©trica. um modo de oscilaã§ã£o de interesse pode ser detectado, e o modo de oscilaã§ã£o de interesse pode ser analisado usando uma transformada de frequãªncia. uma pluralidade de amplitudes do modo de oscilaã§ã£o de interesse em cada sinal de mediã§ã£o pode ser determinada usando uma janela deslizante. a pluralidade de amplitudes pode ser usada para calcular um amortecimento do modo de oscilaã§ã£o de interesse. o amortecimento pode ser calculado resolvendo um sistema de equaã§ãµes linearizadas. o sistema de equaã§ãµes linearizadas pode ser uma estimativa de mãnimos quadrados do amortecimento com base no logaritmo de cada amplitude. se o amortecimento indicar que o modo de oscilaã§ã£o de interesse ã© mal amortecido, uma aã§ã£o de controle pode ser tomada.
