摘　　要：风电机组的高电压穿越(HVRT)技术已被公认为最具挑战性的技术之一,逐渐成为行业内讨论和研究的热点。在研究风电机组HVRT功能必要性的基础上,结合永磁直驱风电机组(PMSG)在电网电压骤升时的暂态特性,提出了一种基于直流回路Chopper电路的永磁直驱风电机组的HVRT功能的低成本技术方法。软件的仿真结果和现场的实际测试数据表明,所提方法可以有效提高永磁直驱风电机组的HVRT能力。HVRT（High-Voltage Ride-Through） function for wind turbine generator has been recognized as one of the most challenging technologies and has gradually become the discussion and research hotspot in this industry. The necessity of HVRT function for wind turbine generators is researched and a low-cost technical method based on the DC-link Chopper circuit is proposed for the HVRT function of PMSG（Permanent Magnet Synchronous wind turbine Generator） according to its transient characteristics during the sudden increase of grid voltage. The simulative results of software and the actual data of site test show that,the proposed method can improve the HVRT performance of PMSG effectively.
