锁相技术在单片机无功功率测量中的应用

Application of PLL in Reactive Power Measurement Using Single-chip Microcomputer

    摘要
  • 摘要: 介绍提高采样精度的锁相环同步采样技术,该方法适用于电网有畸变及频率有波动的电网测量,并提出了实现方案。

     

    Abstract: A measure method to increase the sampling precision is introdueed. The method is PLL(phaselock loops) simultaneously sampling. This method is adapt to measure the electric current, voltage, power and so on in the fluctuated power network.An example has been provided.
