Abstract
En un sistema de proteccion diferenciado de corriente de linea de energia de tres terminales, se obtiene de todas las tres terminales todos los valores de corriente trifasica (IA, IB y IC). Los valores de corriente para cada pase son procesados en tres operaciones de procesamientos sucesivas, usando a su vez los valores de corriente de cada terminal como valores de corrientes locales y la combinacion de los otros dos valores de corriente terminales en cada caso como los valores de corriente remotos. Los valores de corriente local y remota que resultan son luego procesados contra valores preseleccionados que establecen una region de restriccion en el plano de relacion (alfa) de corriente, Los valores de la corriente para cada conjunto de corrientes remota combinada y local que resultan en la relacion estan dentro de la region restringida lo que da como resultado una senal de bloqueo, mientras que los valores que resultan en una relacion fuera de la region dan como resultado una senal de desconexion. Si las salidas de las tres operaciones de procesado estan de acuerda entonces la senal es la salida del sistema. Si hay un desacuerdo, la salida producida cuando la terminal tiene el valor de corriente (I max) mas grande es la corriente local, entonces es la salida del sistema.
