| 摘 要： | 随着系统规模的扩大、互联以及大型机组快速励磁系统的采用,电力系统的低频振荡问题也随之凸现,特别是通过交流输电线互联的系统,由于送电距离长,而联络线又相对较弱,很容易由此引发低频振荡.阐述了电力系统低频振荡的产生机理,讨论了目前常用的分析方法.通过对各种方法的比较分析,阐明了各自的优缺点,并对未来研究的可行方向进行了分析.阐述了目前工程中控制低频振荡的方法,并对其未来发展动向作了进一步的探讨.

| Abstract: | With the fact that system scale expansion,interconnection and the adoption of large-scale generation fast excitation system,the low frequency oscillation problem of power system emerges,especially for the system interconnected by using AC transmission line is easy to initiate low frequency oscillation for long transmission distance,and the junctor is relatively weak.Firstly,this paper discusses the principle oscillation.Secondly, analyzing methods are the focus point.The merits and demerits of every analysi... |
