摘　　要：针对低频振荡对电力系统安全、稳定性的影响,分析了低频振荡机理,并将低频振荡振荡源的定位算法按离线和在线分为两类,介绍了各种算法的原理和步骤,总结了各种算法的优劣,为今后研究低频振荡振荡源定位奠定了基础。Low- frequency oscillation caused by system interconnection has become an important factor endange- ring the safe and stable operation of the grid. In this paper, the mechanism of low frequency oscillation is analyzed. The low -frequency oscillation source localization algorithm are divided into two categories, the offline and online, according to the calculation speed of each algorithm. The paper also introduces he principle and steps of each algo- rithm, and summarizes the merits of various algorithms, which lays the foundation for the study of low frequency os- cillation source localization later.
