Abstract

Control de protección contra sobrevelocidad para sistema de turbina de vapor que incluye un generador eléctrico; una turbina de vapor que incluye una sección de turbina de alta presión y, por lo menos, una sección de turbina de presión más baja que puede funcionar a una primera velocidad de rotación predeterminada; una fuente de vapor; por lo menos una válvula reguladora que sirve para controlar la admisión del vapor a partir de dicha fuente de vapor en dicha sección de turbina de alta presión; un recalentador conectado entre dicha sección de alta presión y por lo menos una sección de presión más baja de la turbina para calentar el vapor conducido a través de él hasta por lo menos dicha sección de turbina de presión más baja.
