Abstract
A method for coupling a rotating device, in particular a steam turbine, and a shaft device, in particular a gas turbine, having the following steps: detecting a differential angle between the shaft device and the rotating device; detecting a differential speed between the shaft device and the rotating device; predicting a coupling angle at which the rotating device and the shaft device would be coupled if the rotating device were accelerated with a known acceleration up to the start of the coupling-in; comparing the predicted coupling angle with a target coupling angle, and calculating therefrom a setpoint acceleration such that the predicted coupling angle matches the target coupling angle.
