摘要：
The main objective of this paper is to report a preliminary study of the effects of the power system stabilizer on the small-signal stability and the damping of low-frequency oscillations of the Vietnam power system which is under fast development and has a longitudinal grid pattern. Spontaneous low-frequency oscillations are potential to occur in the exchange of regional power flow of a power system with longitudinal network structure under normal operation. The method of eigen-analysis is utilized to perform the study of the inter-area oscillations with an emphasis on the oscillation mode with low frequency and light damping. The eigenvalues, eigenvectors, and participation factors associated with the inter-area oscillation modes are calculated in details and possible locations of power system stabilizer are chosen for study accordingly. The results reveal the effectiveness of the power system stabilizer in damping inter-area oscillatory modes and thus the contribution to the improvement of system stability.
