Abstract

Un método para suministrar Regulacion Primaria de Frecuencia en la turbina de vapor de una planta de ciclo combinado comprende la acumulacion de energía, en forma de energía interna del vapor en canerías y domos de las calderas de recuperacion de calor, para utilizarla en los momentos en que la red eléctrica requiere un rápido incremento de la potencia de salida. Se reducen así al mínimo las pérdidas de generacion de energía eléctrica en la turbina de vapor cuando esta opera en modo de Regulacion Primaria de Frecuencia. Cuando las turbinas de gas de ciclo combinado operan en modo RPF, la turbina de vapor disminuye su potencia de salida debido al hecho de que las turbinas de gas deben operar por debajo de su potencia nominal. El método convierte esa disminucion de potencia en la turbina de vapor, en una reserva Rotante util para utilizar en la RPF de esa turbina. Es decir convierte esa Reserva Rotante en una reserva rápida, disponible en pocos segundos, lográndose de ser necesario tiempos de establecimiento inferiores a 10 segundos. El método introduce una serie de pasos innovadores, los cuales constituyen su esencia, que permiten la operacion continua y prolongada en modo RPF de la turbina de vapor de una planta de ciclo combinado, asegurando la efectividad de la regulacion de frecuencia de la red y garantizando en todo momento la estabilidad del proceso de generacion de energía eléctrica de dicha planta de ciclo combinado.
