【Abstract】 The stability of a weakly interconnected system depends mainly upon the damping characteristic difference between the oscillation processes in individual systems.It is well known that a Static Var System (SVS) can affect a power system by changing the power angle of the system.Based on this principle, this paper makes a study of its controlling mode and the calculation method for controlled parameter setting.Taking a four-machine interconnected system as an example, the paper makes an investigation on the effect of damping power oscillation by a SVS installed on the tie-line of this system.更多还原
