摘　　要：串并联型直驱永磁同步发电机(D-PMSG)风电场同一串联簇中机组运行于不同风速时,机组采用传统的最大功率点追踪(MPPT)控制会引起过电压、过调制问题。针对该问题,深入分析了基于轻型直流输电的串并联型D-PMSG风电场机组的运行特性,提出了适用于串并联型风电场的控制策略。最后对所提方法进行了仿真对比分析与实验验证,仿真与实验结果表明该方法可保证机组在限压期间安全运行。For series-parallel topology wind farm,adopting traditional control strategy will lead to over voltage and overmodulation when the wind turbines in same series branch under different wind speed.To solve this problem, the operation characteristics of series-parallel direct-drive permanent magnet synchronous generator （D-PMSG） wind farm is investigated,and a control strategy suitable for series and parallel topology is proposed.In addition, simulation and experimental results verify the method can achieve the purpose of maximum wind power capture in a safe range.
