Abstract

Se proporciona protección diferencial de corriente para un aparato de energía de terminales múltiples, tal como una línea de transmisión de energía. Las corrientes medidas en cada una de las terminales múltiples se usan para calcular una corriente diferencial y una corriente de restricción, que luego se convierten en una primera corriente equivalente y una segunda corriente equivalente de un aparato de energía de dos terminales equivalente. En el aparato de energía de dos terminales equivalente, una corriente diferencial derivada de la primera y segunda corrientes equivalentes es sustancialmente igual a la corriente diferencial del aparato de energía de terminales múltiples original. De manera similar, una corriente de restricción derivada de la primera y segunda corrientes equivalentes es sustancialmente igual a la corriente de restricción del aparato de energía de terminales múltiples original. La primera y segunda corrientes equivalentes pueden usarse en un análisis del plano alfa para determinar si o no desconectan el aparato de energía de terminales múltiples.
