摘要
鉴于小干扰稳定在现代电力系统中的重要地位,在对系统进行建模、仿真、计算的基础上,得到系统振荡模式的特征值、阻尼比、频率和机电回路比,并通过对多机系统的计算分析,研究电力系统稳定器(PSS)的配置策略对低频振荡的抑制作用,从而得出对电力系统小干扰稳定性能的改进办法。
Based on the important position of small-signal stability in modern power system, the paper gets the eigenvalues, the damping ratio, the frequency and the machine oscillation mode related ratio of system oscillation by modeling, simulating and computing to the systems. And then some multiple-generator systems are computed and analyzed to study the effect of the configuration of power system stabilizer （PSS） on low-frequency oscillation suppression. As a result, an improved method about the small-signal stability of power system can be found out.
