Abstract

PERFECCIONAMIENTOS EN LOS SISTEMAS DE CONTROL DE AGUA DE ALIMENTACION PARA UNA CENTRAL NUCLEAR.COMPRENDE CUATRO SUBSISTEMAS: EL SUBSISTEMA DE CALCULOS LOGICOS (50) SELECCIONA EL MODO DE OPERACION DEPENDIENDO DEL ESTADO DE LAS ESTACIONES MANUALES/AUTOMATICAS, LAS BOMBAS DE AGUA DE ALIMENTACION Y LAS VALVULAS DE CONTROL; EL SUBSISTEMA DE CALCULOS DE ESTIMA DE PERTURBACION (52) Y EL SUBSISTEMA DE CALCULOS DE ALIMENTACION DIRECTA MODIFICADA (54), EL PRIMERO TIENE UN MODELO DINAMICO Y EL SEGUNDO UN MODELO DE ESTADO DE REGIMEN DERIVADO DEL MODELO DINAMICO. EL PRIMERSUBSISTEMA PRODUCE SALIDAS INDICATIVAS DE LAS DESVIACIONES DE VARIABLES QUE SE UTILIZAN COMO ENTRADAS EN EL SEGUNDO SUBSISTEMA PARA PRODUCIR SEÑALES DE CONTROL PARA DETERMINAR POSICIONES DE VALVULAS Y VELOCIDADES DE BOMBA Y SITUAR LOS VALORES DE FLUJO EN LOS EXIGIDOS; EL SUBSISTEMA DE CALCULO DE REALIMENTACION PROPORCIONAL (56) MODIFICA LA DINAMICA NATURAL DEL SISTEMA CONJUNTO PARA OBTENER UN TIEMPO DE RESPUESTAS MAS RAPIDO.
