| 摘要: |
| 以统一潮流控制器为研究对象，针对其逆变器输出的线电压中可能含有的谐波成分，设计出一种变压器接线方式，通过这种变压器接线方式，逆变器输出的线电压中的一些谐波成分将会被抑制。同时将特定谐波消去调制技术应用于统一潮流控制器逆变器的控制中，可将变压器接线方式所不能消除的谐波成分中的低次谐波成分消除掉。 |

| Abstract: |
| Since the output line voltage of an inverter may have harmonic component ,a kind of transformer connection mode is designed for UPFC(Unified Power Flow Controller)to restrain it.SHEPWM(Special Harmorious Elimination Pulse Width Modulation)technique is also applied to the control of inverter in UPFC to eliminate the low-order harmonic components,which may not be res-trained by the transformer connection mode. |
| Key words: UPFC,inverter,SHEPWM,harmonic aberrance rate, |
