摘要
基于正则形二阶变换定义的非线性稳定因子,对三机交直流互联电力系统低频振荡模式的非线性相关作用进行分析,得出了正则形变量的稳定区域,进而判断出系统的稳定性。时域仿真结果证明了非线性稳定因子的有效性。
Basing on the nonlinear stability factor defined with normal second-order transformation,the nonlinear of low-frequency oscillation mode in the three-phase AC/DC interconnected power system is analyzed,and the stable region is fixed to judge the stability of the system.The simulation results show the feasibility of the nonlinear stability factor.
