摘　　要：随着电网系统风电渗透率的提高,对所在地区电网的电能质量以及电能调度产生重大影响。为研究风电场在大扰动下的宏观动态响应特性,对风电场进行动态等值建模非常重要。针对风电场的动态等值建模研究,文章首先对现今主流的风机类型及其模型结构进行了简要介绍;然后对等值建模方法中的降阶法、单机等值法以及多机等值法做了比较和详细阐述,并对等值参数计算和集电网络等值进行了概述;最后总结了风电场动态等值建模尚存在的挑战,并对未来的研究方向进行了展望。With the increase in the penetration rate of grid-connected wind power and the continuous expansion of the scale of wind farms,the integration of wind power into the grid will have a significant impact on the power quality and power dispatching of the regional power grids.In order to study the macroscopic dynamic response characteristics of wind farms under large disturbances,it is very important to carry out dynamic equivalent modeling of wind farms.Aiming at the research on dynamic equivalent modeling of wind farms,this paper briefly introduces the current mainstream wind turbine types and their model structures.Then,the reduced-order method,the single-machine equivalent method and the multi-machine equivalent method of the equivalent modeling methods are compared and elaborated,and the calculation of equivalent parameters and the equivalent value of the collector network are summarized.Finally,the existing challenges in equivalent modeling of wind farms are summarized,and the future research directions are prospected.
