Abstract

SISTEMA DE MONITORAMENTO E RESPOSTA DE ENERGIA ELéTRICA Um sistema de monitoramento (10) e de resposta (22) para energia elétrica utiliza sensores de campo eletromagnético (12a-c) localizados remotamente ao lado dos condutores de fase. O sistema determina variáveis de sistema desconhecidas para uma ou mais linhas de energia trifásicas (4) com base nos valores mensurados obtidos dos sensores de campo e, em alguns casos, valores do sistema de energia conhecidos. Para uma configuração física dada, os sensores de campo poderão incluir sensores de campo magnéticos ou elétricos, e os valores de sistema conhecidos bem como as variáveis de sistema desconhecidas poderão incluir correntes de fase, voltagens de fase e distâncias que definem a configuração tísica do sistema, O equipamento de resposta poderá ser uma tela, um dispositivo de interrupção de circuito, um regulador de voltagem, um suporte para a barriga de voltagem, um banco capacitor, equipamento de comunicação, ou sistema de reportagem.
