Abstract

"COMUNICAçãO DE FASE CONCOMITANTE EM TWACS". Um método para comunicação concomitantemente em cada fase de uma rede de distribuição de energia elétrica (N). Um primeiro sinal de saída (SO1) é transmitido em uma fase (AN-A) de um barramento (S) por uma unidade de modulação de saída. A unidade é liberada tão logo o primeiro sinal de saída (SO1) é transmitido de maneira que a unidade possa transmitir um segundo sinal de saída (SO2) em uma segunda fase (BN-B ou CN-C) do barramento. O segundo sinal de saída é concomitantemente transmitido com um sinal de entrada (IB1) enviado em resposta ao primeiro sinal de saída (SO1). A unidade é novamente liberada, tão logo o segundo sinal de saída (SO2) é transmitido, de maneira que a unidade possa transmitir um terceiro sinal (SO3) sobre a terceira fase (BN-B ou CN-C) do barramento. Este terceiro sinal de saída é transmitido concomitantemente com um segundo sinal de entrada (IB2) enviado em resposta ao segundo sinal de saída (SO2). O método permite comunicações concomitantes em todas as três fases da rede (N).
