摘　　要："十一五"末至"十二五"期间,随着国家特高压骨干网架的逐渐形成并联入江西,江西电网内部结构以及与其它省网区域间的联络情况发生较大变化,低频振荡将成为江西电网安全稳定的主题之一。为此,采用基于特征值分析法的小干扰稳定分析方法对江西电网2015年夏季大负荷方式的小干扰稳定进行了研究,研究表明江西电网正常大方式的各种振荡模式的阻尼特性较好。The 1 000 kV backbone grid will be gradually formed in the future 5 to 10 years.The internal structure of Jiangxi power grid and the tie-line between Jiangxi network and other provincial network will change greatly. The low frequency oscillation will be one of the themes of the security and stability of Jiangxi power grid. This paper has researched The small signal stability of the operational method of Jiangxi power grid in the summer 2015 by using the small signal stability analysis based on eigenvalue analysis method. The results show that all kinds of oscillation method of Jiangxi power grid have good damping characteristic.
