| 摘要: |
| 介绍了针对三相四线制系统谐波检测所提出的p—q—r法，详细讨论了p—q—r法对中线电流的抑制效果。针对电网电压畸变时补偿不完全的情况，提出采用前置滤波的方法，对采样的畸变电网电压信号进行滤波，去除谐波成分，保留基波成分。仿真结果表明，采用该方法能够完全补偿电流谐波分量，消除电压畸变对结果的影响。 |

| Abstract: |
| The p-q-r method is introduced, which is applied in three-phase four-wire system to detect harmonics. Its effect on eliminating neutral current is researched in detail. It is suggested to apply prefil-ter for removing the harmonic components when the compensation is incomplete because of system voltage distortion. The simulative results show that the proposed method compensates the harmonic currents completely and eliminates the effects of voltage distortion. |
