摘　　要：风电并网研究中,风电机组模型众多但都缺少有效性验证,给电力系统分析带来很多不便。为此,依据国际电工技术委员会(International Electrotechnical Commission,IEC)提出的风力发电机组建模标准草案,在DIg SILENT/Power Factory软件平台上搭建双馈型风力发电系统通用模型,通过故障条件下风电机组对低电压穿越响应的实测结果与仿真结果的比较,以及根据西班牙并网导则中对风电机组模型准确性评估指标进行模型的误差评估,确定模型的正确性和有效性。完成当前主流双馈风力发电机组模型的有效性验证工作,其将提高风电系统并网分析结果的准确性。For the sake of lack of wind turbine models validation in the study of power system interconnected with wind power, which brings a lot of inconvenience to the analysis of power system, the generic model of doubly fed induction generator(DFIG) system is established according to the draft standard for modeling of wind turbine generator system released by International Electrotechnical Commission(IEC) under DIg SILENT/Power Factory software platform. With the comparison between the test and simulation result of low voltage ride through dynamic response of wind turbine, and the model error evaluation according to Spanish grid code, the accuracy and effectiveness of the model is validated. This paper has finished the validation of the most common DFIG model, the job will contribute to improve the accuracy of the analysis on power system interconnected with wind turbines.
