Abstract

SE DESCRIBE UN PROCEDIMIENTO PARA EL PROCESADO ANALOGICO Y MEDICION BINARIA DE VALORES DETECTADOS MEDIANTE SENSORES EN UNA PLANTA HIDRAULICA O TERMICA DE GENERACION ENERGETICA. LOS VALORES DE MEDIDA ANALOGICOS Y BINARIOS DETECTADOS EN CONDICIONES OPERACIONALES UNIFORMES Y NO UNIFORMES, TALES COMO VALORES DE ENTRADA, VALORES DE SALIDA, RESTRICCION DE CARGA Y CONDICIONES DE EMERGENCIA, SON SUMINISTRADOS A UN BANCO (12) DE DATOS EN TIEMPO REAL, DESPUES DE QUE HAN SIDO CONVERTIDOS EN LAS SEÑALES DIGITALES CORRESPONDIENTES Y PREPARADAS TAMBIEN DE FORMA CORRESPONDIENTE ASI COMO PREPROCESADAS (22,23). EL BANCO (12) DE DATOS DE TIEMPO REAL ESTA DISTRIBUIDO EN UNA SISTEMA DE ORDENADOR DIGITAL, QUE CONSISTE EN AL MENOS DOS ORDENADORES DIGITALES ENLAZADOS MUTUAMENTE MEDIANTE UN ANILLO Y DISPONIENDO DE UNA UNIDAD CENTRAL, UNA UNIDAD DE MEMORIA Y UN DISPOSITIVO DE INDICACION. EL SISTEMA DE ORDENADOR DIGITAL ESTA PROVISTO ADEMAS CON UN SISTEMA (13,14) EXPERTO Y CON MODULOS (15,16,17,18) DE CALCULO QUE DETERMINAN LOS DATOS DE MAQUINA INSTANTANEA A PARTIR DE LOS VALORES DE MEDIDA. ESTOS VALORES SON COMPARADOS POR MEDIO DEL SISTEMA (13,14) EXPERTO CON LOS DATOS DE LA MAQUINA CALCULADOS O CON LOS DATOS MEDIDOS DE LA MAQUINA EN EL ESTADO ORIGINAL Y ALMACENADOS EN EL BANCO (12) DE DATOS DE TIEMPO REAL, DONDE SON EVALUADOS. ADICIONALMENTE, EL SISTEMA (13,14) EXPERTO REALIZA UN ANALISIS (25) DE TENDENCIA Y UN DIAGNOSIS ON-LINE DEL ESTADO DE LA PLANTA DE ENERGIA. DESDE EL MOMENTO QUE ES SIEMPRE CONOCIDO EL PROCESO DEL ESTADO INSTANTANEO DEL GENERADOR Y/O Y DE LA TURBINA, NO SE REQUIERE LA FIJACION DE PLANES DE OPERACIONES DE MANTENIMIENTO Y PUEDE SER ADOPTADA UN MANTENIMIENTO DEPENDIENDO DEL ESTADO CORRESPONDIENTE DE LA PLANTA.
