Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA LA PROTECCION DE EXCITADORES DE SALIDA CONTRA SOBRECARGAS Y CORTOCIRCUITOS, EN DONDE SE UTILIZA UN CIRCUITO QUE FUNCIONA A VARIOS NIVELES DE TENSION DE CONTROL Y EN DONDE AL MENOS UN EXCITADOR DE SALIDA (Q31, Q41) ES CONTROLADO EN UNA SITUACION NORMAL POR UN VALOR DE REFERENCIA (BVD) AJUSTADO INDEPENDIENTEMENTE DE UN CONTROL EXTERNO (I1-I7), MIENTRAS QUE EN UNA SITUACION DE CORTOCIRCUITO O SOBRECARGA EL EXCITADOR RECIBE UNA TENSION DE CONTROL DURANTE CORTOS INSTANTES SOLAMENTE, Y EN DONDE EL VALOR DE REFERENCIA COMIENZA A DECAER RAPIDAMENTE CUANDO LA CORRIENTE DE CARGA DEL EXCITADOR DE SALIDA EXCEDE DE UN LIMITE ESTABLECIDO.
