FIELD: turbines or turbomachines.
SUBSTANCE: method relates to managing gas turbine assembly during start-up or shutdown. Method comprises controlling the speed of the output shaft rotation and, at the same time, controlling the speed of the input shaft rotation, after controlled rotation speed of the output shaft will become above zero or below the set speed limit of slow rotation for a specified allowable time interval.
EFFECT: optimally limiting the time interval during which the gas turbine unit, including the gas seal, rotates at a speed in the range of slow rotation.
