THEORYOF THEMODULATEDREACTANCE SOLUTTION FORSUBSYNCHRONOUS RESONANCE

One solutionfor the subsynchronous resonancephenomenaknownas "torsionalinteraction" is a controlledshuntreactorconnectedto thetermi- nalsof theaffectedgenerators.A deviceuising this techniqueis calledthe "DynamicStabilizer".This paper developsa mathematical model of the subsyn- chronousresonancephenomenaand the actionof the Stabilizer.It includesa numericalexampleto illu- strate the equationsand providesinformationon requiredequipmentratingsandcontrolsettings.
