| 摘要: |
| 在现有单相电路基波电流分离法基础上,分析了锁相环相位检测误差和畸变电压对谐波和无功电流检测的影响,得出由锁相环及畸变电压引起的相位检测误差不影响谐波电流的检测,但对谐波和无功电流的综合检测以及直流侧电压调整有影响的结论.提出了一种谐波和无功电流综合检测新方法,采用无锁相环、提取功率角的方式,实现了畸变电压下单相电路谐波和无功电流的综合检测.仿真结果验证了该检测方法应用于有源电力滤波器中的有效性. |

| Abstract: |
| Based on the fundamental current separation method for single - phase circuit,the influences of distorted voltage and phase detection error of PLL(Phase Locked Loop) on the detection of harmonic and reactive power current are analyzed,which shows that,the phase detection error does not influence the harmonic current detection,but affects the integrative detection of harmonic and reactive power current,as well as the DC voltage regulation. A new method is put forward to realize the integrative detection of h... |
