摘　要：以特征结构分析法为理论基础,对包含风电场(基于恒速恒频机组构成)的电力系统的静态电压稳定问题进行研究.通过对相关比、参与因子和潮流雅可比矩阵、收缩有功和无功雅可比矩阵最小模特征值的分析,揭示电压和角度不稳定的机理和失稳模态,并提供相关节点的参与程度和系统的稳定裕度信息.仿真结果表明:基于恒速恒频机组构成的风电场及其附近节点具有较强的无功-电压参与程度,是系统电压失稳的关键区域.在IEEE10机39节点电力系统中加入基于恒速恒频机组的风电场并网的简化模型进行仿真研究,采用连续潮流算法对系统平衡解流形进行追踪,对鞍结分岔点的计算采用分岔理论中的直接算法,工具软件采用MATLAB7.04.
