摘    要:基于注入功率空间上小扰动稳定域的定义,提出了多机电力系统小扰动稳定域的实用边界计算方法.首先分析了二机电力系统小扰动稳定域的特点,发现其边界具有固定的规则形状;然后,引入分群和二机等值的方法,对多机系统先分群和等值,再搜索Hopf分岔集.由于全部分群子空间上的Hopf分岔集和原系统的Hopf分岔具有映射关系,所以等值简...

关 键 词:电力系统  小扰动稳定域  Hopf分岔  实用边界

Abstract:Based on the small signal stability region defined on power injection space,a calculation method of applied boundary for multi-power systems is presented.Firstly,in the two-machine power system,the characteristic of the small signal stability region is studied,and it is found that its boundary has a regular shape in the 2-dimension plane.Secondly,using the technology of groups division and system equivalent of two-machine,the search of Hopf bifurcation set in multi-machines systems is implemented.In the pap...
Keywords:power system  small signal stability region  Hopf bifurcation  applied boundary
