摘要
A voltage source is connected in series with the neutral secondary winding on a generator step-up transformer through an electrical reactance. A control circuit and a pair of thyristor banks are employed to apply the voltage source to the transformer winding to dampen subsynchronous resonance currents and to prevent torsional mode vibrations from occurring within the generator.
