The first Torsional Dynamic Stabilizers were installed at the San Juan generating station to control subsynchronous oscillations between the turbine-generator units and the series capacitor compensated transmission system. A description of these devices and their application at this plant is the subject of this paper. A field test program which included control of self-excited torsional oscillations is described. Test results verify that the Dynamic Stabilizers do control San Juan subsynchronous oscillations and allow unrestricted use of the compensation.
