用于直驱型风力发电系统的变流器

Converter for direct-drive wind power system

分布式风力发电系统是具有广泛应用前景的风电技术。文章针对分布式小型直驱风力发电机组的需求,设计了适用于该系统的变流装置。将软开关技术和双环控制策略应用到该变流器的设计中,有效地降低了风电在变流过程中的功耗,提高了效率和供电质量,并大大地减少了经济成本。通过实验证明了设计的正确性和可靠性。

Distributed wind power generation system is widely used wind power technology.In this paper, a converter device applicable to the small distributed direct-drive wind turbine was designed. The soft-switching technology and double-loop control strategy are applied to the converter design, which effectively reduce the loss of wind power in converting process, improves the effi- ciency and quality of power supply, and greatly reduces the economic cost. The experimental results prove the correctness and reliability of the design.
