摘　　要：随着风电装机容量在电网中所占比重的不断增加,大规模风电并网对电网的影响也越来越严重。根据风电基地风电场实际运行数据,分析了大规模风电并网对电力系统的影响,包括风电场正常运行时的无功、谐波等问题,以及故障时对电网暂态电压稳定性的影响。根据风电场在运行中存在的问题,提出了提高风电机组低电压穿越能力,加强对风电场动态无功补偿装置运行管理等措施。Along with the increasing proportion of wind power capacity in the grid,the impacts of large-scale grid-connected wind power on the grid are becoming more and more serious.According to the actual operating data of Jiuquan wind power base,this paper analyzes the impacts of large-scale wind power on the power system,including the problems,such as reactive power,harmonics,etc.under normal operation,and on the transient voltage stability of the grid under fault conditions.Considering the problems of wind farms under operation,the paper proposes the measures to improve the low voltage ride through capability of wind turbines,and strengthen the dynamic reactive power compensation device operation and management of wind farms.
