摘　　要：针对某风电场多次发生的次同步振荡事件,对该风电场进行资料收集和电能质量测试,分析次同步振荡产生的原因。在此基础上,通过时域仿真研究、实测数据验证等,进一步研究风电场次同步振荡的发生机制,并针对性地制定解决方案。所开展的工作可为大规模风电场并网下次同步振荡抑制及供电电能质量改善提供借鉴。The present work originated from the repeatedly events of subsynchronous oscillation encountered by an actual wind farm.It first carried out information collection and power quality test on the wind farm and found out the causes of subsynchronous oscillation.Consequently it further studied universally the underlying mechanism of wind farm subsynchronous oscillation through time-domain simulation and actual-data-based verification,and also tentatively formulated the specific countermeasures.This work may provide useful information for suppressing subsynchronous oscillation and improving power supply quality in grids integrated with large-scale wind generations.
