| 摘 要： | 运用虚拟仪器技术取代传统的谐波监测分析装置。测试有源电力滤波器的调试效果。将电网电压、滤波前后的电流经互感器变换后送给采集卡。然后将采集的数据经USB通信接口送到计算机，经数字滤波处理后，采用FFT进行谐波分析，比较滤波前后的电流畸变率和电压畸变率。验证了有源滤波器对谐波和无功的治理效果。

| Abstract: | The traditional harmonic monitoring and analysis device was replaced by the virtual instrument technology for detecting active power filter effect. The result of voltage and current were transformed by the transformer to capture cards, and then to a computer by USB communication interface, after digital filtering processing, to make use of high-precision FFT to analyze harmonic. The current distortion factor and voltage distortion rate before and after filtering were compared, to verify the treatment effect of the active filter for harmonics and reactive. |
