Abstract

UN SISTEMA DE ALIMENTACION (10) COMPRENDE UNA FUENTE CA MULTIFASE (12) QUE ESTA PREVISTA EN UN CONVERTIDOR CA-CC (14). LA SALIDA CC DEL CONVERTIDOR (14) SUMINISTRA ENERGIA AL BUS CC (16), QUE PROPORCIONA ENERGIA A UN BUS DE SUMINISTRO SEGUNDARIO (42) Y CARGAS ELECTRICAS (38, 40). EL CONVERTIDOR (14) ESTA CONECTADO AL BUS CC (16) POR UN CONMUTADOR PRINCIPAL (22) QUE SE PUEDE CONTROLAR DESDE UN PROCESADOR DE CONTROL PRINCIPAL (30) PARA DESCONECTAR LOS DOS. DE UN MODO SIMILAR, EL BUS DE SUMINISTRO (44), LA CARGA (38) Y LA CARGA (40) SE CONECTAN AL BUS CC (16) MEDIANTE CONMUTADORES SEGUNDARIOS (46), QUE SE PUEDEN CONTROLAR CADA UNO PARA EFECTUAR LA DESCONEXION A TRAVES DE LA ACCION DE LOS PROCESADORES DE CONTROL SEGUNDARIOS (48) RESPECTIVOS. CUANDO UNO CUALQUIERA DE LOS BUSES DE SUMINISTRO SEGUNDARIO (44) O CARGAS (38, 40) SOLICITA ENERGIA DEL CONVERTIDOR (14), SE PASA UNA SOLICITUD REQUERIDA POR EL PROCESADOR DE CONTROL SEGUNDARIO RESPECTIVO (48) AL PROCESADOR DE CONTROL PRINCIPAL (30) A TRAVES DEL BUS DE DATOS (32). EL PROCESADOR DE CONTROL PRINCIPAL (30) DETERMINA ENTONCES SI LA SOLICITUD REQUERIDA ES LEGAL BASADA SOBRE UNA ENERGIA PERMISIBLE MAXIMA REQUERIDA Y TAMBIEN CONSIDERARA LA SUMA CUMULATIVA INSTANTANEA DE ENERGIA REQUERIDA A SUMINISTRAR. SI LO REQUERIDO ES LEGAL, SE DEVUELVE UNA AUTORIZACION DE SOLICITUD AL PROCESADOR DE CONTROL SEGUNDARIO (48), Y LA ENERGIA PUEDE SER OBTENIDA. SI LA PETICION NO ES LEGAL, EL PROCESADOR DE CONTROL PRINCIPAL (30) PUEDE SOLICITAR A UNO O MAS PROCESADORES DE CONTROL SEGUNDARIOS (48) QUE REDUZCAN ENERGIA DE LA CARGA ELECTRICA A TRAVES DE LA OPERACION DE LOS INTERRUPTORES AUTOMATICOS (24) EN LOS RESPECTIVOS CONMUTADORES SEGUNDARIOS (46). ALTERNATIVAMENTE EL PROCESADOR DE CONTROL SEGUNDARIO (48) QUE REALIZA LA PETICION PUEDE SER PROVOCADO PARA EFECTUAR LA REGENERACION DE LA ENERGIA. EN EL CASO DE AVERIAS SERIAS, EL PROCESADOR DE CONTROL PRINCIPAL (30) PUEDE PROVOCAR QUE EL BUS DC SE REDUZCA POR EFECTO DE LOS INTERRUPTORES AUTOMATICOS (24) DENTRO DEL CONMUTADOR PRINCIPAL (22).
