摘　　要：大规模风电汇集系统网架结构复杂、风机数量众多、控制环节多样,既可能与外部电网的串补装置、直流输电、弱交流线路、火电机组发生动态交互,亦可能存在内部风电机群之间、风机不同控制环节之间的动态交互,深入探究其小干扰振荡的产生机理、振荡特性、影响因素对电力系统的安全稳定运行至关重要。文章从大规模风电汇集系统与外部电网动态交互引发的小干扰振荡、大规模风电汇集系统内部小干扰振荡2个方面梳理回顾了风电汇集系统小干扰稳定性研究的历程和主要研究成果,评析了目前主要研究方法的优势及缺陷,并探讨展望了大规模风电汇集系统小干扰稳定性领域未来的研究方向。The large-scale wind power collection system has complex grid structures,a large number of wind turbines,and diverse control systems.It may not only dynamically interact with the series compensation devices,the DC transmission,the weak AC lines,and the synchronous generators of the external power grid,but also exist internal dynamic interactions between wind turbine groups or between different control systems of wind turbines.The in-depth exploration of the generation mechanism,oscillation characteristics,and influencing factors of its small disturbance oscillation are essential to the safe and stable operation of the power system.This paper reviews wind power from two aspects:the small disturbance oscillation caused by the dynamic interaction between the large-scale wind power collection system and the external grid,and the small disturbance oscillation inside the large-scale wind power collection system.The history and main results of the small disturbance stability research of the collection system are reviewed,as well as the advantages and disadvantages of the current main research methods.The future research directions in the field of small-disturbance stability of large-scale wind power collection system are discussed and proposed.
