| 摘 要： | 提出了一种适用于三相三线制不平衡系统的任意次谐波电流检测方法。该方法基于d-q旋转坐标变换,采用不同的旋转角速度旋转,以检测出不同次谐波电流的正负序分量。把所得的正负序分量相加便可得到所要检测的谐波分量。经过理论分析和仿真验证说明了该方法的正确性。

| Abstract: | A new detection method for random harmonic current which was suitable for 3-wire and 3-phase unbalance system was put forward.The method was based on d-q rotating coordinate transformation,rotated in diffe-rent rotating angular velocity to detect the positive and negative phase sequence of different order harmonic current.The harmonic component to be detected could be got by adding the positive and negative phase sequence.Theoretical analysis and simulation proved the correctness of the method. |
