中文摘要：
针对4机11节点电力系统,通过详细模型下的仿真发现小扰动稳定域边界上会出现几何形状的突变现象。进一步研究表明,所发现的小扰动稳定域边界的突变是由于对应边界处的主导振荡模式在不同模式间发生了跳跃变化。同时指出,存在造成小扰动稳定域边界突变的其他原因,边界上主导模式的跳跃仅是小扰动稳定域边界突变的一种机理解释。
英文摘要：
The sudden change of the boundary of small signal stability region （SSSR） is shown through the studies of a 4-generator 11-bus power system models. It is found that this type of sudden change is due to jumpings of the critical oscillation mode between different modes on the corresponding boundary of SSSR. Meanwhile, it is illustrated that there is other mechanism that may result in this sudden change and it could be concluded that jumpings of critical oscillation mode is only one of the causes that lead to drastic changes of the boundary＇s shape of SSSR.
