摘　　要：准确的风电并网试验平台,对风电场并网控制保护等相关问题研究至关重要。本文以实时数字仿真系统RTDS为基础,旨在建立符合实际工程情况的风电场经柔性直流输电系统并网实时仿真平台。首先筒述双馈式风力发电机基本原理及背靠背PWM换流器的控制方式,在Rack1中构建其仿真模型并通过阵风实验验证其有效性.然后在Rack2中建立采用电流矢量控制的双端柔性直流输电系统仿真模型,最后通过Rack之间的通讯建立完整的风电经柔性直流输电系统并网模型。经渐变风实验证明,该实时仿真试验平台具备较好的动态响应特性和准确性.对风电研究具有很好的借鉴意义。Accurate wind power experimental platform is essential for control and protection research of wind power. This paper aims to establish a wind power real time simulation platform in line with the actual project situation. Flatly, the basic fundamental of DFIG and control of back-to-back PWM converter have been brief introduced. Then the simulation model of DHG has been built in Raekl and examined by gust test. Meanwhile the double-ended VSC-HVDC based on current vector control has been modeled in Rack2. Finally, though communication between the Racks, the entire model has been completed. Proved by gradient wind experiment, the real-time simulation platform of wind power have good dynamic response and accuracy, which can be used for wind power research.
