Abstract

Sistema de supervisión de velocidad para un sistema de control de turbina que proporciona unas señales representativas de la velocidad de la turbina, destinadas a ser utilizadas para controlar el funcionamiento de la turbina, que incluye un dispositivo de detección de velocidad para detectar la velocidad de la turbina, caracterizado porque incluye un primer dispositivo de conversión controlado por dicho dispositivo de detección para generar al mismo tiempo una primera señal de velocidad digital y una primera señal de velocidad digital y una primera señal de velocidad analógica; un segundo dispositivo de conversión similar a dicho primer dispositivo de conversión controlado por dicho dispositivo de detección de velocidad para generar, al mismo tiempo, una segunda señal de velocidad digital y una segunda señal de velocidad analógica; un tercer dispositivo de conversión controlado por dicho dispositivo de detección de velocidad para generar una tercera señal de velocidad analógica; un primer dispositivo controlado por dichas primera y segunda señales de velocidad digitales y dicha tercera señal de velocidad analógica para seleccionar una de las primera y segunda señales de velocidad digitales, sin preferencia, como siendo representativa de la velocidad de la turbina para utilizarla en el control de funcionamiento de la turbina por debajo de un nivel de velocidad predeterminado; y un segundo dispositivo controlado por dichas primera, segunda y tercera señales de velocidad analógica, con el objeto de seleccionar una de dichas primera y segunda señales de velocidad analógicas, sin preferencia, como siendo representativa de la velocidad de la turbina con el objeto de utilizarla para controlar el funcionamiento de la turbina por encima de un nivel de velocidad predeterminado.
