FIELD: electricity.
SUBSTANCE: device is designed to reduce subsynchronous resonance in electrical transmission systems and includes facilities (16), (17) to define voltage components from the side of stator windings in generator (9) with one or more discrete frequencies and calculation means taking into account the results of the said calculations, voltage to be added to the specified voltage of stator windings to reduce subsyncronous resonance in electrical system and a circuit (20) configured so that calculated voltage can be added to the specified voltage of stator windings.
EFFECT: improved reliability and effectiveness of means allowing for reducing effects of subsynchronous resonance.
