Abstract

Un sistema para reducir al mínimo las pérdidas de energía de planta de energía ocasionada substancialmente por estrangulamiento de válvula de flujo de vapor, mientras que se mantiene la planta de energía a un nivel deseado de generación de energía, la planta de energía incluye una caldera para general vapor a una presión de estrangulamiento de caldera que se regula mediante un punto de ajuste de presión; una turbina de vapor que tiene una pluralidad de válvulas de flujo de vapor para regular la cantidad de vapor generado a través de las mismas; un medio de control de válvula regulado por una señal de referencia que corresponde al nivel de generación de energía deseado, para colocar la pluralidad de válvulas de flujo de vapor en un estado de conformidad con un patrón predeterminado de colocación de válvula, basado en el valor de la señal de referencia; y un generador eléctrico impulsado por la turbina de vapor para generar energía eléctrica.
