双馈风力发电机风电场故障特征分析及对继电保护影响研究

摘要

以山西朔州地区右玉风电场为例，根据右玉风电场实际参数，利用电力系统计算机辅助设计电磁暂态仿真软件，搭建了双馈风电场系统仿真模型，分析研究了双馈风力发电机风电场220 kV联络线故障特征及对继电保护的影响。%According to the actual parameters of Youyu wind farm,a simulation model of double-fed wind farm system based on PSCAD was established. The fault characteristics of 220 kV tie-line in wind farm with double-fed wind generators were analyzed and their impacts on relay protection were studied.
