摘　　要：目前,我国电网呈现出多回大容量直流输送,大规模风光新能源发电的新形态。混联电网的复杂结构和元件新特性使得大干扰后交直流系统的稳定性面临严峻挑战。本文主要综述了大干扰稳定分析的研究进展,将大干扰稳定分析的研究方法分为了逐步积分法、渐进展开法、数值逼近法、直接法和其他方法五大类,并展开介绍了几种常见大干扰稳定分析方法,对比不同方法各自的优势与不足,为未来混联电网大干扰稳定性分析的深入研究提供助力。Nowadays,the Chinese power grid exhibits a new architecture of multi-infeed HVDC transmission with large-scale wind and photovoltaic new power generation interconnection.The complex structure and new component characteristics of hybrid power grid make the stability of AC/DC systems more vulnerable after large disturbance.This paper mainly reviews the research progress of large disturbance stability analysis and divides the analysis methods into five classes:step-by-step integration method,asymptotic expansion method,functional approximation method,direct method and other methods.Moreover,several common large-disturbance stability analysis methods are introduced.The advantages and disadvantages of the methods are discussed in this paper,which are thought to be useful for further study on large-disturbance stability in the future.
