摘要： An apparatus for reducing subsynchronous resonance phenomena in a power transmission system. A determining arrangement determines components of the voltage from stator windings of a generator with one or more discrete frequencies. A calculating arrangement calculates, on a basis of the result of the determining, a voltage to be added to the voltage from the stator windings for reducing phenomena in the power system and an arrangement adapted to add the voltage calculated to the voltage from the stator windings.
