摘　　要：风电机组并网容量的不断增加,对系统安全稳定运行的影响越来越明显。研究大规模风电并网对系统小干扰稳定及阻尼特性的影响并提出相应的控制策略成为电力系统备受关注的课题,为此,对近年来学者们对该课题的研究成果展开综述,介绍3种不同类型的风电机组和小干扰稳定性的基本概念,总结不同类型风电机组对系统小干扰稳定性的影响,概括风电机组电力系统稳定器(power system stabilizer,PSS)提高系统阻尼的方法,同时对该课题的研究前景进行展望。Ever-increasing grid-connection capacity of wind power generator may result in more and more obvious affect on safe and stable operation of the system, and research on influence of large-scale wind power grid-connection on small interfering stability and damping characteristic of the system as well as proposal of related control strategies becomes focused is- sues for power system. Therefore, this paper summarizes research results of these issues in recent years and introduces basic concepts of three different kinds of wind power generators and small interfering stability. It also summarizes affects of dif- ferent wind power generators on small interfering stability of the system, generalizes methods for improving system damping by power system stabilizer and forecasts research prospect of these issues.
