摘要：
Subsynchronous oscillation may cause the unstable torsional vibration of turbine-generator shaft system, and even damage the generator shaft, endangering the safe operation of power system. Based on the simulation, this paper uses Static Var Compensator to damp subsynchronous oscillation by utilizing extra voltage control and modal separation control. The subsynchronous oscillation effect of Static Var Compensator suppressing IEEE first benchmark model under the above two control strategies is analyzed and compared in detail. It is shown that both of the control strategies can help to damp subsynchronous oscillation, but the effect of modal separation is relatively better on the whole.
