摘要
聚焦直流型风电场单极性输出与直流电网双极性传输的匹配问题,以隔离式双向全桥DC/DC子单元模块为基础,面向实验室环境搭建风电场单双极性转换DC/DC接口变换器实验样机。进而构建了一套直流风电传输过程的低压小容量等效实验模型,阐述了该接口变换器的基本原理与控制策略。最后通过实验证明该等效实验模型和控制策略具备正确性和有效性。
It focused on the matching problem between the unipolar output of DC-based wind farm and bipolar trans- mission of DC gird.Based on the cell of isolated bi-directional full-bridge DC/DC topology, a DC/DC interface convert- er for DC-based wind farm is built in the lab.And consequently, an equivalent hardware experimental model for DC wind power transmission process is constructed in the low-voltage and small-capacity level.The basic principles and control strategies of the interface converter are introduced.Finally, experimental results vertify the correctness and ef- fectiveness of the experimental model and control strategy.
