Abstract

Une référence de pression de vapeur principale permettant la commande d'une chaudière, et une réference d'ouverture des soupapes de commande d'une turbine, sont données en fonction de la demande de charge instantanée (Ld) d'une installation. Les soupapes de commande de la turbine 400-407 sont réglées de manière à annuler l'écart entre la puissance réelle fournie par l'installation et la demande de charge instantanée. L'écart entre l'ouverture réelle des soupapes de commande et la référence d'ouverture des soupapes est introduit dans des dispositifs de réglage (PI) dans lesquels sont exécutées une opération proportionnelle et une opération intégrale et dont les signaux de sortie servent à corriger la référence de pression de vapeur principale, si bien que l'ouverture des soupapes finit par coincider avec la référence d'ouverture voulue correspondant à la demande de charge instantanée. Centrales thermiques.A main steam pressure reference allowing the control of a boiler, and a reference for opening the control valves of a turbine, are given as a function of the instantaneous load demand (Ld) of an installation. Turbine 400-407 control valves are set to cancel the difference between the actual power supplied by the installation and the instantaneous load demand. The deviation between the actual opening of the control valves and the opening reference of the valves is fed into regulating devices (PI) in which a proportional operation and an integral operation are performed and the output signals of which serve to correct the main vapor pressure reference, so that the opening of the valves eventually coincides with the desired opening reference corresponding to the instantaneous load demand. Thermal power stations.
