Abstract

Procédé de régulation d'une turbine à vapeur à surchauffeur intermédiaire. On effectue la comparaison entre la valeur de consigne n, et la valeur réelle ni de la vitesse et on transmet à un dispositif RV à circuit de régulation une valeur de réglage y tirée de la différence entre les valeurs de consigne et réelle. La pression px du surchauffeur intermédiaire est transformée en une grandeur de réaction k qui tend vers zéro et cette grandeur k est soustraite de la grandeur y dans le circuit de régulation. Application : turbine à fonctionnement sans oscillation.
