Abstract
Sistema para elegir de manera razonada la modalidad de control de una central eléctrica accionada por turbina de vapor que tiene una caldera para generar vapor que se aplica a una turbina de vapor conectada mecánicamente con un generador eléctrico que produce energía eléctrica a un nivel de producción de energía deseado y que incluye un regulador principal de caldera para controlar el grado de calentamiento de la caldera, sirviendo dicho regulador de caldera para generar una pluralidad de señales de estado actual representativas del estado de control de la central, un regulador principal de turbina para controlar una pluralidad de válvulas de admisión de vapor de la turbina, sirviendo dicho regulador de turbina para generar una segunda pluralidad de señales de estado actual representativas del estado de control de la central, funcionando simultáneamente dichos reguladores principales de caldera y turbina en una de las modalidades de control de regulación en función de la caldera y de regulación en función de la turbina y un dispositivo de selección para efectuar la conmutación de la modalidad de control de dicha central entre dichas modalidades de regulación en función de la caldera y de regulación en función de la turbina, estando caracterizado dicho sistema porque incluye unos medios para gobernar de manera razonada dicho dispositivo de selección para asegurar la conmutación del control de la central en dicha modalidad de control de regulación en función de la caldera de acuerdo con un primer grupo de condiciones predeterminadas de control de la central establecidas a partir de dichas primera y segunda pluralidades de señales de estado actual generadas, y unos medios para gobernar de manera razonada dicho dispositivo de selección para asegurar la conmutación de dicho control de central en dicha modalidad de control de regulación en función de la turbina de acuerdo con un segundo grupo de condiciones predeterminadas de control de la central establecidas a partir de dichas primera y segunda pluralidades de señales de estado actual generadas.
