Abstract
METODO PARA PREDECIR LA TRANSICION OPTIMA ENTRE EL FUNCIONAMIENTO A PRESION CONSTANTE Y EL FUNCIONAMIENTO A PRESION VARIABLE, PARA MEJORAR EL RENDIMIENTO DE UNA CENTRAL ELECTRICA DE TURBINA DE VAPOR DE ARCO PARCIAL DURANTE VARIACIONES DE SALIDA DE POTENCIA AJUSTANDO DINAMICAMENTE LOS VALORES DE PUNTOS DE VALVULA DURANTE EL FUNCIONAMIENTO DE TURBINA; SE DETERMINA LA PRESION DE CAMARA IMPULSORA EN VARIOS PUNTOS A PRESION CONSTANTE; PARA CADA PAR DE PUNTOS SE COMPUTA UNA PRESION DE PUNTO DE TRANSICION OPTIMO A PRESION CONSTANTE PARA EFECTUAR LA TRANSICION ENTRE MODOS DE PRESION VARIABLES Y CONSTANTES; SE CONVIERTE ESTA PRESION EN UN PORCENTAJE DE DIFERENCIA DE PRESION; SE USA LA PRESION EN CADA PUNTO PARA CALCULAR UNA PRESION PARA EFECTUAR LA TRANSICION DE MODOS BASADA EN EL PORCENTAJE; ESTAS PRESIONES CALCULADAS SE COMPARAN CON VALORES MEDIDOS DE PRESION Y SE FUERZA LA TRANSICION DE MODOS CUANDO LOS VALORES SON IGUALES.
