DRIVING MECHANISM OF POWER GENERATOR (VERSIONS), METHOD TO CONTROL FREQUENCY OF POWER GENERATOR DRIVING MECHANISM ROTATION, TURBINE (VERSIONS) Russian patent published in 2012 - IPC F03D11/02 F03B15/06 

FIELD: power engineering.

SUBSTANCE: driving mechanism for a power-generating device 5 provides for a link between a power generator 20 and a turbine 10, which rotates with varying frequency. The rotating driving mechanism provides for a generator 20 rotation at the outlet with a fixed rotation frequency. The driving mechanism includes a differential gear box (16), which has two output shafts. One drives the generator 20 by means of the shaft 26, and the other one drives an electric machine 30 by means of the transfer 18. The varying reactive torque provided by the electric machine 30, may be used for control of torque and rotation frequency at the outlet shaft 26. The input torque from the turbine 10 is measured in the point of application of gear box 16 reaction, and this measurement is used to change reactive moment provided by the electric machine 30.

EFFECT: inertia in a gear box and inertia of an electric machine are reduced to zero for provision of almost instantaneous change of reactive torque and by means of this for more efficient control of output shaft rotation frequency.
