摘　　要：随着新型电力系统的发展,以风力发电为代表的新能源被广泛使用,受电力电子器件开关特性的影响,风电机组并网时不可避免地产生谐波,在大规模并网时,风电集群设备间的交互影响进一步加剧谐波问题。为此,提出了一种基于实测数据的风电机组谐波特性建模方法,用于分析实际工程中风电机组的谐波特性。首先,明确了不同频次谐波特性的关键影响因素,提出了风电机组的谐波特性分析模型,简化了风电机组谐波建模的整体过程。其次,结合实际风电集群拓扑结构,建立了风电集群聚合谐波模型,明确了风电机组之间的谐波交互影响程度,量化了计及风电机组间耦合影响的单体与集群的关联关系。最后,通过实验分析了直驱风电机组的谐波特性,通过仿真验证了集群聚合谐波模型的准确性,提高了风电集群建模的准确度。With the development of new power systems,renewable energy represented by wind power generation is widely utilized.Due to the influence of switching characteristics of electronic devices,wind turbines inevitably generate harmonics during the grid connection.During large-scale grid connections,the interaction between wind power cluster devices further exacerbates harmonic issues.Therefore,the measurement data based modeling method for harmonic characteristics of direct-drive wind turbines is proposed,which is used to analyze the harmonic characteristics of wind turbines in engineering practice.Firstly,the key influencing factors of harmonic characteristics at different frequencies are identified,and a harmonic characteristic analysis model for wind turbines is proposed,which simplifies the overall process of harmonic modeling for wind turbines.Secondly,based on the actual topology of wind power clusters,an aggregation harmonic model of wind power clusters is established,which clarifies the interactive effect of harmonics among wind turbines and quantifies the correlation between individual units and clusters considering the coupling effects between wind turbines.Finally,the harmonic characteristics of direct-drive wind turbines are validated by experiments;the accuracy for the aggregated harmonic model of clusters is validated by simulations,and the accuracy of wind power cluster modeling is improved.
