摘　　要：电力系统小信号分析方法是当前学术界研究的热点,但是目前大量使用的特征值分析方法和小干扰下的时域仿真方法仍然不能完全地解决系统的分析问题。首先对研究电力系统的常用模型和小信号分析的主要方法进行了简述。接着,对电力系统小信号模态分析的主要研究方法进行了回顾和分析,并对现阶段小信号分析最新的理论(正规型方法和模态级数法)和研究成果进行了详细地论述。最后对该领域的研究进行了总结和展望。Small-signal analysis in power system is the hot researching point which is concerned all over the world. But the small-signal stability analysis and the time-domain simulation method, which are widely used currently, still can＇t solve problems of the power system absolutely. The power system common model and the main researching methods of small-signal analysis are reviewed. The latest theories and researching results of small-signal analysis, normal form method and modal series method are introduced in detail. The researching field of small-signal modal analysis is summarized and prospected.
