| 摘 要： | 研究了适用于小干扰稳定分析的双馈感应电机的降阶模型.首先,建立描述双馈感应电机电磁过程的8阶详细模型;以此为基础,根据双馈感应电机各个物理量的衰减快慢关系提出了保留锁相环动态的简化2阶模型,并分析了影响该模型稳定性的因素;最后,采用李雅普诺夫稳定性判别法,通过算例比较了2阶模型与详细模型以及依据传统方法提出的6阶模型的小干扰稳定边界.结果表明:与6阶模型相比,文中提出的2阶模型的稳定边界更符合8阶详细模型对系统稳定性的描述.

| Abstract: | A reduced order model of double fed induction generator (DFIG) for small signal stability analysis is investigated. Firstly,an 8th order detailed model to describe the DFIG electromagnetic process is established. Based on the 8th order model,a simplified 2nd order model with the phase-locked loop (PLL) dynamic state is presented according to the attenuation speed of the relationship between various physical quantities of the DFIG,and the factors of affecting the simplified 2nd order model stability are anal... |
