摘要
简单介绍电力系统中的一些分叉现象,着重分析了引起电压失稳的鞍结分叉(SNB)、霍普夫分叉(HB)以及奇异诱导分叉(SIB)等三种主要分叉形式的定义和分岔发生的条件,并通过数值仿真具体讨论了电压稳定性与鞍结分叉、霍普夫分叉之间的关系,力求从动力系统的角度来理解并解释电压稳定性。最后,展望了分叉理论在电压稳定分析中需进一步深入研究的问题。
Some different kinds of bifurcation phenomena in electric power system are simply introduced. Saddle-node bifurcation,hopf bifurcation and singularity induced bifurcation,which cause mainly voltage instability, are emphatically analyzed. Then, the relationship between voltage stability and two main kinds of bifurcation is discussed specifically by numerical simulation to settle and understand voltage stability. At last, other further research fields of bifurcation theory applied in voltage stability analysis is predicted in the future.
