摘　　要：电压电流的频率和相位角的准确获取对于电机在线监测具有重要的意义,锁相环技术被成熟地应用于电网领域的相位角跟踪中。然而,在变频变压条件下,传统的锁相环存在频率适应性差、相位输出有较大误差的问题,因此,提出了一种基于双同步坐标系变换的锁相环技术,通过电机电压电流正负序分量的分离实现相位角的准确跟踪。最后,搭建了基于STM32的锁相环跟踪监测系统,试验结果证明了该方法的有效性和实用性。The accurate acquisition of the frequency and phase angle of the voltage and current is of great significance for the on-line monitoring of the motor,and the phase-locked loop technology is maturely applied to the phase angle tracking in the field of power grid.However,under the condition of VVVF,the traditional phase-locked loop has the problem of poor frequency adaptability and large error in phase output.Therefore,a phase-locked loop technology based on the double synchronous coordinate system transformation is proposed.The phase angle can be accurately tracked by separating the positive and negative sequence components of voltage and current of the moter.Finally,a phase-locked loop tracking monitoring system based on STM32 is established,and the test results prove the effectiveness and practicability of the method.
