多机电力系统振荡模式阻尼分配与传递

Damping Apportionment and Transference of Oscillation Modes in Multi-machine Power System

根据电力系统特征分析法，分析了系统励磁运行方式变化对多机系统阻尼的影响。通过各种因素对系统阻尼特性影响的分析，对低频振荡产生机理有了进一步的理解，从而有助于采取必要的预防措施。

According to the Eigen-analysis on power system, this paper studies the influence of different exciting operation modes on the damping of multi-machine system. Through analysis of different factors, mechanism of low frequency oscillation is further eluciated. Hence, the necessary measures to prevent it from happening can be taken.
