摘　　要：功角稳定性和电压稳定性是电力系统稳定性的两个方面。功角稳定和电压稳定常常交织在一起,若孤立地对某一方面进行研究都是不全面的。对功角稳定和电压稳定的基本概念及两者的关联性研究现状进行论述。分析了小干扰分析法、能量函数法、分叉理论、向量场正规形法、模态级数法等方法,讨论了它们的分析原理、特点、存在的不足和近几年来的研究成果。最后对该领域的研究进行总结并指出了模态级数法可望成为功角稳定和电压稳定关联性研究的有力工具。Voltage and angle stability are two aspects of power system stability, which are always interweaved. If a certain aspect is researched isolatedly, it is not comprehensive. The contents of angle stability and voltage stability and the current status of relationship study between them are discussed. Small disturbance analysis, energy function, bifurcation theory, normal forms of vector fields, and modal series theory are analyzed and their analysis principles, characteristics, existing flaws and research results in recent years are briefly discussed. Finally, the research field of relationship between angle and voltage stability is summarized and prospected. And it is pointed out that modal series method would be a powerful tool for the study of the relationship between angle and voltage stability.
