1.
To research control characteristics of permanent magnet synchronous generator(PMSG) for direct-driven variable-speed constant-frequency(VSCF) wind energy conversion system(WECS),the principle of back-to-back converters was discussed,then the work principles of encoder and sensorless control were analyzed.
为了研究直驱型变速恒频风电系统永磁同步发电机(PMSG)的控制特性,在分析背靠背变流器工作原理的基础上,详细讨论了有无速度传感器控制的工作原理,有传感器控制采用高精度增量式编码器,无传感器控制采用基于锁相环的控制策略对PMSG的转速和相位进行观测。
2.
Based on analysis to the principle of back-to-back converter for direct-driven variable speed constout frequency(VSCF) WECS,phase lock loop(PLL) based sensorless control strategy was adopted to determine the speed and phase angle of PMSG,and its work principle and realization method are analyzed in detail.
在分析直驱型变速恒频风电系统背靠背变流器工作原理的基础上,采用锁相环无速度传感器控制策略对永磁同步发电机的速度和相位进行观测,对其工作原理和实现方法进行了分析。
