Abstract

SE ESTABLECE UN CIRCUITO DE BLOQUEO DE PERDIDA DE SINCRONISMO CON DOS ZONAS ADICIONALES EN EL PLANO DE IMPEDANCIA, CON EL CIRCUITO QUE DETERMINA EL TIEMPO QUE LA IMPEDANCIA DE SECUENCIAS POSITIVAS EMPLEA PARA MOVERSE ENTRE LAS DOS ZONAS. LOS ELEMENTOS DE DISTANCIA PARA LAS ZONAS SELECCIONADAS DE PROTECCION PARA EL RELE SON BLOQUEADOS SI LA IMPEDANCIA SE MUEVE ENTRE LAS DOS ZONAS A UNA VELOCIDAD INFERIOR A UN PRIMER UMBRAL. SIN EMBARGO, UNA SEÑAL DE DISPARO RESULTA SI LA VELOCIDAD DE CAMBIO ES MAYOR QUE EL PRIMER UMBRAL PERO INFERIOR A UN SEGUNDO UMBRAL, QUE INDICA UNA OSCILACION INTERNA INESTABLE. ADEMAS, UNA ZONA DE ANTEOJERA SE ESTABLECE EN EL PLANO DE LA IMPEDANCIA DENTRO DE LAS DOS ZONAS DE PROTECCION ADICIONALES. SI LA IMPEDANCIA DE SECUENCIAS POSITIVAS QUE ENTRA EN LA ZONA QUE SE INTRODUCE EN ESA ZONA NO SE NUEVE DE ESA ZONA DENTRO DE UN CIERTO TIEMPO DURANTE POR OTRA PARTE UNA CONDICION DE PERDIDA DE SINCRONISMO, LAS SEÑALES DE BLOQUEO SON DETERMINADAS.
