摘　　要：针对兆瓦级直驱风电变流器中永磁同步电机无传感器控制技术的重要作用,根据永磁同步电机的数学模型,提出了一种基于电机反电动势闭环锁相环的永磁同步电机位置的估算算法,并进行了仿真和实验验证。仿真和实验结果表明:利用该估算方法能够准确计算出永磁同步电机的位置,实现对直驱风力发电系统中的永磁同步电机的有效控制。According to the important role of sensorless control technology for permanent magnet synchronous motor （PMSM） of megawatt direct-drive wind power converter, an estimation algorithm based on back electromotive force closed phase-locked loop （PLL） of motor was proposed, to which, simulation and test verification were conducted. Results show that the PMSM position can be calculated accurately by the estimation algorithm so as to achieve effective control over the PMSM in direct-drive wind power generation systems.
