Abstract
Un sistema de protección de corriente diferencial para una línea de energía de múltiples terminales, el cual incluye un sensor de corriente para detectar una corriente en la terminal local, un controlador para la sincronización de tiempo de la terminal local y las terminales remotas y un módulo de detección de falla para detectar una falla en la línea de energía de múltiples terminales cuando la corriente diferencial excede a un valor umbral. El controlador incluye un módulo de intercambio de medición de tiempo para intercambiar datos de marca de tiempo con las terminales remotas, un reloj de alcance superior para intercambiar datos de marca de tiempo con las terminales remotas y un reloj de alcance inferior para indexar la corriente en la terminal local. Un primer período de tiempo del reloj de alcance superior es N veces un segundo período de tiempo del reloj de alcance inferior, en donde N es un número de múltiples terminales. El controlador incluye un módulo de cálculo de desplazamiento de reloj para determinar el desplazamiento de tiempo promedio con base en los datos de marca de tiempo desde las terminales remotas y la terminal local.
