| 摘 要： | 通过对abc三相坐标进行d-q坐标变换的方法,提出了一种新型的基于d-q坐标变换的谐波与无功电流的检测方法.该方法通过对三相电压与电流进行d-q变换后对相应的分量进行分离的方法实现对谐波与无功电流的检测.详细地说明了基于d-q坐标变换的谐波与无功电流检测算法的流程,给出了具体的框图并其特点进行了总结;同时利用PSCAD/EMTDC软件对基于d-q坐标变换的谐波与无功电流检测方法进行仿真分析.仿真结果表明,所提方法可以准确及时地实现电网中谐波与无功电流的检测. |

| Abstract: | A method of harmonic and reactive currents detection based on d-q coordinates transformation for three-phase voltage and current is proposed, which separates the responding components after d-q transformation to realize the current detection. The detection algorithm is introduced in detail, its block diagram is given and its features are summarized. Simulative analysis is carried out with PSCAD/EMTDC, which shows that the harmonic and reactive currents are detected precisely and timely. |
| Keywords: | APF d-q transformation reactive current detection harmonic current detection PSCAD simulation |
