摘要
在大型区域互联电网中,低频振荡已成为影响系统的广域安全稳定运行的重大问题。随着广域相量测量系统WAMS的投入,低频振荡的在线分析成为可能。通过在线模式辨识可以实现低频振荡在线监测以及施加适当的阻尼控制。本文主要讨论基于环境激励的低频振荡在线分析方法,对这类方法的原理、特点、应用做了系统的阐述,并探讨存在的问题和进一步研究的方向。
In large-scale inter-connected power grids, low frequency oscillation has become a serious threat to the wide-area safe and stable operation of power systems. The application of WAMS （ Wide Area Measurement System） opens the way to the online analysis of low frequency oscillation, which can be achieved through the online identifica- tion and monitoring, and applying the appropriate damping Control. This paper reviews the online analysis methods based on ambient excitation, emphatically, their fundamental principle, characteristics and application. Finally, some existing problems and further research direction are discussed.
