摘　　要：目前关于双馈风机控制器参数辨识方法的研究,鲜有涉及适用于故障穿越分析的完整控制器参数的高效辨识。针对该问题,提出了基于主导特性解析的双馈风机控制器参数高效并行辨识方法。基于主流型号的厂家封装模型对双馈风机的电磁暂态响应特性进行测试分析,获得典型变流器控制结构;通过分析机组各控制器参数与动态响应特性的主导关系,揭示了控制器参数可高效并行辨识的基本原理,提出了故障穿越和转子侧/网侧控制器内外环控制器参数辨识的最佳激励方案和高效并行辨识方法;基于MATLAB/Simulink仿真平台,构建了双馈风机白盒电磁暂态仿真模型,通过与厂家封装模型在故障穿越全过程的响应特性对比,证明所提方法能够更加准确、高效地辨识控制器参数。Currently,research on the identification methods of doubly fed induction generator(DFIG)controller parameters rarely addresses efficient identification of complete controller parameters suitable for fault ride-through(FRT)analysis.To tackle this issue,an efficient parallel identification method of DFIG controller parameters based on dominant response characteristic analysis is proposed.The electromagnetic transient response characteristics of DFIG are tested and analyzed based on mainstream manufacturer-encapsulated model,by which the typical converter control structure is obtained.By analyzing the dominant relationships between various controller parameters and dynamic response characteristics of DFIG,the basic principle of efficient parallel identification of controller parameters is unveiled.The optimal excitation schemes and efficient parallel identification methods for FRT and inner/outer loop controller parameters of the rotor-side controller and grid-side controller are proposed.Based on the MATLAB/Simulink simulation platform,a white-box electromagnetic transient simulation model of DFIG is constructed.Compared with the response characteristics of the manufacturer-encapsulated model throughout the FRT process,it is proved that the proposed method can identify controller parameters more accurately and efficiently.
