METHOD FOR OPERATING TURBINE ENGINE AFTER FLAME EXTINCTION

摘要

FIELD: machine engineering.;SUBSTANCE: method for slowing down the turbine rotor (12) of a turbine engine (1) in which at least one electric generator (30) is connected to the turbine rotor (12). The brake system (40) is connected to at least one electric generator (30) so as to use at least one electric generator (30) for applying the braking torque to the turbine rotor (12). After flame extinction, the brake system (40) is used to dissipate the kinetic energy present in the turbine engine (1) after flame extinction by means of at least one electric generator (30). At that the braking torque applied to the turbine rotor (12) is changed during the deceleration of the turbine rotor (12), depending on the rotational speed of the turbine rotor (12).;EFFECT: reduction of the shut down process of the turbine engine after flame extinction, as it causes the turbine rotor to decelerate faster, reduction of vibrational load on the turbine engine or elements connected to the turbine engine.;14 cl, 4 dwg
