Abstract

UN ELEMENTO DIRECCIONAL (40) QUE PRODUCE UNA CANTIDAD DS}O RELACIONADA A UNA IMPEDANCIA DE FUENTE DE SECUENCIA CERO DE UN SISTEMA DE POTENCIA RELATIVA A LA LOCALIZACION DEL ELEMENTO DIRECCIONAL(40), DESDE VALORES DE CORRIENTE DE SECUENCIA CERO (I{SUB,B} Y UN VALOR AJUSTADO DE TENSION DE SECUENCIA CERO (3V{SUB,O}).LA CANTIDAD DE IMPEDANCIA ({DS}O) SE COMPARA ENTONCES CONTRA UNA PRIMERA Y SEGUNDA CANTIDAD UMBRAL (Z{SUB,OF}YZ{SUB,OR}) PARA IDENTIFICAR LA DIRECCION DE UN ERROR. POSTERIORMENTE, EL ELEMENTO DIRECCIONAL DE TENSION POLARIZADO DE SECUENCIA CERO PUEDE SER COMBINADO CON OTROS ELEMENTOS DIRECCIONALES INDIVIDUALES, QUE INCLUYE UN ELEMENTO DIRECCIONAL DE CORRIENTE POLARIZADO DE TENSION DE SECUENCIA NEGATIVA PARA FORMAR UN ELEMENTO INDIVIDUAL UNIVERSAL PARA ERRORES DE DESEQUILIBRADO, EN EL QUE LOS ELEMENTOS DIRECCIONALES INDIVIDUALES OPERAN EN UNA SECUENCIA PARTICULAR, CON LOS OTROS ELEMENTOS DIRECCIONALES ESTANDO BLOQUEADOS PARA OPERAR SIN UN ELEMENTO DIRECCIONAL ANTERIOR EN LA SECUENCIAPROPORCIONA UNA INDICACION DE DIRECCION.
