摘　　要：大容量海上风电机组的接入改变了传统电力系统结构,给电网带来了谐波等问题,影响了电能质量。为抑制海上风电机组产生的低次谐波,文章首先建立了海上风电机组并网电流的低次谐波理论模型;然后,在仿真软件ETAP上搭建海上风电机组仿真模型,验证不同出力情况下风电场的输出谐波特性;最后,基于风电场输出谐波特性,提出变异系数(Variation Coefficient,VC)综合赋权法对风电场有源滤波器(APF)进行优化配置,提升了风电场谐波的治理效果。基于实际算例验证了所提方法的有效性。With the proposal of the"double carbon"goal,the structure of the new power system with new energy as the main body has changed significantly,especially the access of large capacity offshore wind power units,which has brought harmonic and other power quality problems to the grid.In order to study the characteristics of low frequency harmonics generated by fan connection,firstly,a theoretical model of low frequency harmonic content in the grid-connected current of fan is established.Then,an offshore wind power simulation model is built on the simulation software ETAP to verify the output harmonic characteristics of the wind farm under different output conditions.Finally,based on the output harmonic characteristics of the wind farm,the variation coefficient synthetic weighting method is proposed to optimize the configuration of the active power filter(APF)in the wind farm to improve the control effect of the harmonic in the wind farm,and the effectiveness of the method is verified by simulation based on an actual example.
