METHOD OF CONNECTING TWO SHAFTS Russian patent published in 2018 - IPC F02C6/02 

FIELD: power engineering.

SUBSTANCE: invention relates to power engineering. Method of connecting the first shaft containing the first blade machine and the generator connected to the mains, with the second shaft containing the second blade machine, is carried out by means of overrunning clutch. Method includes the steps of: a) rotating the second shaft at an initial speed of rotation that is lower than the frequency of rotation of the first shaft; b) measuring the frequency of the power grid; c) measuring the difference angle between the first and second shafts; d) accelerating the second shaft with the acceleration value arising with the involvement of the network frequency, the difference angle and the initial speed measured in step b) the way the overrunning clutch connects the two shafts to each other for a given target connection angle.

EFFECT: invention allows to increase the efficiency of connection of turbine shafts.
