Abstract
A method for synchronising a turbine with an AC network having a network frequency, having the following steps: A) accelerating the turbine up to a stated rotational speed, without taking into consideration a difference angle between the turbine and the AC network; B) detecting a difference angle between the turbine and the AC network; C) accelerating or decelerating the turbine in such a way that the differential speed follows a target trajectory, wherein the target trajectory is a trajectory that indicates a target rotational speed depending on the detected difference angle, such that a target angular position that is suitable for a synchronous supply is achieved between the turbine and AC network.
