Title (EN) TURBINE SPEED AND ACCELERATION LIMITER
(FR) LIMITEUR DE VITESSE ET D'ACCÉLÉRATION DE TURBINE
Abstract:
(EN) Method for controlling steam admission into a steam turbine (1), the turbine (1) comprising a high pressure casing (2), at least one reduced pressure casing (3, 4, 5, 6) and an admission steam control system (13), the high pressure casing (2) and at least one reduced pressure casing (3) comprising control valves (8, 10) for steam admission. The steam admission control system (13) manages the following steps: determining at least one of the speed (14) and the acceleration (15) of the turbine (1); comparing the determined speed and/or acceleration respectively with a predefined speed threshold value (16) and a predefined acceleration threshold value (17); when the determined speed and/or acceleration are superior to the predefined threshold value (18, 19), the control system (13) activates a speed and acceleration limiter (20).
(FR) Cette présente invention concerne un procédé de régulation de l'admission de vapeur dans une turbine à vapeur (1) comprenant un carter haute pression (2), au moins un carter à pression réduite (3, 4, 5, 6) et un système de commande de vapeur d'admission (13). Le carter haute pression (2) et au moins un carter à pression réduite (3) comprennent des soupapes de commande (8, 10) pour l'admission de vapeur. Le système de commande d'admission de vapeur (13) gère les étapes suivantes : déterminer la vitesse (14) et/ou l'accélération (15) de la turbine (1); comparer la vitesse et/ou l'accélération déterminée respectivement à une valeur seuil de vitesse prédéfinie (16) et une valeur seuil d'accélération prédéfinie (17); lorsque la vitesse et/ou l'accélération déterminée sont supérieures à la valeur seuil prédéfinie (18 19), le système de commande (13) active un limiteur de vitesse et d'accélération (20).
