摘要
文章针对船用永磁同步电机中存在的谐波电流问题,提出了一种基于SOGI的谐波电流抑制方法。该方法通过对电网电流进行SOGI变换,得到了电流中的谐波分量,并采用PI控制器对谐波电流进行补偿。最后,通过仿真和实验验证了该方法的有效性和优越性。
In this paper,a harmonic current suppression method based on SOGI is proposed for the harmonic current problem in marine permanent magnet synchronous motors.In this method,the harmonic component in the current is obtained by SOGI conversion of the grid current,and the PI controller is used to compensate for the harmonic current.Finally,the effectiveness and superiority of the proposed method are verified by simulation and experiment.
