A method may be used in controlling the connection of a multiple phase power source to a plurality of capacitors. Each phase of the multiple phase power source is electrically connectable to at least one of the plurality of capacitors through a switching device. The method comprises, for each phase of the multiple phase power source, determining a first voltage of a power signal for the respective phase of the power source using a first voltage divider that is electrically connected to a first terminal of the switching device for the phase. The method further comprises, for each phase, determining a second voltage across a capacitor that is electrically connected to a second terminal of the switching device for the phase. The second voltage is determined using a second voltage divider that is electrically connected to the second terminal of the switching device for the phase. The method further comprises, for each phase, generating a close signal configured to cause the switching device for the phase to close and electrically connect the respective phase of the power source to the capacitor when the difference between the first voltage and the second voltage is approximately zero.

    Abstract: A presente invenção descreve um método para controle de sobretensões durante a manobra de religamento de linhas de transmissão com compensação reativa em derivação. Após o disjuntor abrir uma LT, a interação entre a admitância transversal da linha e a indutância do reator de compensação reative faz com que a tensão entre os pólos do disjuntor assuma forma oscilatória (batimento). O ponto ótimo para voltar a fechar o disjuntor corresponde à região onde a amplitude do batimento da tensão entro os pólos do disjuntor é mínima. O método desenvolvido apresenta maior segurança na determinação da primeira região de mínimo do batimento, independente da passagem da onda de tensão por zero. Tal procedimento permite também contar com maior margem de tempo para operar o disjuntor já que a detecção da região ótima para o religamento ocorre com vários ciclos de freqüência fundamental de antecedência. Este método deve ser incorporado na lógica de controle de um relé digital para religamento tripolar de linhas de transmissão gerando um novo relé digital para religamento tripolar adaptativo de linhas de transmissão com compensação reativa em derivação.
