PROCEDE ET SYSTEME DE COMMANDE D'ARRET D'UNE TURBINE A GAZ.

摘要

The device has a sensor (1) for measuring speed of a shaft of a gas turbine (T), and a control unit (3) for controlling a level of opening of fuel supply valves (V) of the turbine. A temperature sensor measures temperature at an exhaust of the turbine. The control unit includes a regulation unit (10) for regulating deceleration of the shaft to determine degree of the opening of valves for supplying fuel from the speed of the shaft and the temperature at the exhaust of the turbine. A storing unit i.e. memory (6), stores an ideal profile for deceleration of the shaft. An independent claim is also included for a method for controlling stopping of a gas turbine.
