FIELD: this group of inventions refer to synchronous generators namely to receiving initial data for definition of transitional and established regimes of current values of the parameters of a synchronous generator essential for compensation of spinning vibrations of its rotor.
SUBSTANCE: the indicated group of inventions is directed on development of modes and an arrangement for its execution for compensation of spontaneously excited (not obligatory periodical) of short term, durable or constantly operating spinning vibrations of the rotor of a synchronous generator. The arrangement for compensation of the spinning vibrations of the rotor in a working regime has a sensor of an angular position of the rotor of the generator, a module-meter of current values of momentary angular speed of the rotor of the generator, a filter of upper frequencies, a module-meter of current values of angular (spinning) vibrations of the rotor, a driving generator of numerical analogs of textual signals of control over the synchronous generator, a commutation arrangement, a generator of numerical analogs of textual signals of control over the exciter, an arrangement of feeding of control voltage on the contacts of the exciter of the synchronous generator, a module-identifier of the dynamic link " an exciter- a synchronous generator and an arrangement of forming numerical analogs of working signals of control for compensation of spinning vibrations of the rotor of a synchronous generator connected between themselves in corresponding mode.
EFFECT: the described arrangement realizes two variants of the modes of compensation of spinning vibrations of the rotor.
