Abstract
"ESTIMAçãO DE ESTADO DE REDE DE TRANSMISSãO DE ENERGIA ELéTRICA". Em um processo, programa de computador e sistema para estimar um estado de uma rede de transmissão de energia elétrica, medições de fasor temporais são efetuadas por unidades de medição de fasor (1) localizadas em um primeiro conjunto de locações (11,12) através da totalidade da rede, e uma pluralidade de tensão e/ou corrente em um segundo conjunto de locações é estimado, onde as locações dos primeiro (11, 12) e segundo conjuntos de locações é estimado, onde as locações dos primeiro (11, 12) e segundo conjuntos de locações são mutuamente distantes, e um status de elementos de rede (L4,L5,13) que são remotamente localizados em relação às unidades de medição de fasor é inferido das medições de fasor e dos fasores estimados. Em uma variante preferencial da invenção, os elementos de rede são linhas de transmissão (L1, L8), aparelhamento de comando elétrico, transformadores de tomadas variáveis sob carga, dispositivos de compensação (13) ou dispositivos FACTS, e as informações de status descrevem ser um elemento de rede (L4,L5,13) está eletricamente conectado com ou desconectado da rede.
