Abstract

LA PRESION DE IMPULSO EN CADA UNO DE LOS MULTIPLES PUNTOS DE VALVULA SE DETERMINA DURANTE EL FUNCIONAMIENTO DE LA TURBINA A PRESION CONSTANTE. PARA CADA PAR DE PUNTOS DE VALVULA ADYACENTES, SE CALCULA UNA PRESION OPTIMA DE TRANSICION A PRESION CONSTANTE PARA EFECTUAR LA TRANSICION DE UNO A OTROS MODOS DE FUNCIONAMIENTO A PRESION DESLIZANTE Y A PRESION CONSTANTE. LA PRESION OPTIMA DE PUNTO DE TRANSICION A PRESION CONSTANTE PARA CADA PAR DE PUNTOS DE VALVULA SE CONVIERTE EN UN PORCENTAJE DE LA DIFERENCIA DE PRESION ENTRE LOS PARES ADYACENTES DE PUNTOS DE VALVULA. LA PRESION DE CAMARA DE IMPULSO SE UTILIZA PARA CALCULAR UNA CORRESPONDIENTE PRESION DE CAMARA DE IMPULSO PARA EFECTUAR LA TRANSICION DESDE UN MODO AL OTRO BASANDOSE EN EL PORCENTAJE DE DIFERENCIA DE PRESION. SE CONSIGUE MEJORAR EL RENDIMIENTO OPERACIONES DE UNA CENTRAL TERMOELECTRICA MEDIANTE EL AJUSTE DINAMICO DE LOS VALORES DE PUNTOS DE VALVULA DURANTE EL FUNCIONAMIENTO DE LA TURBINA.THE IMPULSE PRESSURE AT EACH OF THE MULTIPLE VALVE POINTS IS DETERMINED DURING THE OPERATION OF THE CONSTANT PRESSURE TURBINE. FOR EACH PAIR OF ADJACENT VALVE POINTS, AN OPTIMAL CONSTANT PRESSURE TRANSITION PRESSURE IS CALCULATED TO CARRY OUT THE TRANSITION FROM ONE TO OTHER MODES OF OPERATION AT SLIDING PRESSURE AND CONSTANT PRESSURE. THE OPTIMAL PRESSURE OF CONSTANT PRESSURE TRANSITION POINT FOR EACH PAIR OF VALVE POINTS BECOMES A PERCENTAGE OF THE PRESSURE DIFFERENCE BETWEEN ADJACENT PAIRS OF VALVE POINTS. THE IMPULSE CHAMBER PRESSURE IS USED TO CALCULATE A CORRESPONDING IMPULSE CHAMBER PRESSURE TO EFFECT THE TRANSITION FROM ONE MODE TO THE OTHER BASED ON THE PRESSURE DIFFERENCE PERCENTAGE. IT IS POSSIBLE TO IMPROVE THE OPERATING PERFORMANCE OF A THERMAL ELECTRIC POWER PLANT BY DYNAMIC ADJUSTMENT OF VALVE POINT VALUES DURING THE OPERATION OF THE TURBINE.
