-
摘要: 介紹提高采樣精度的鎖相環同步采樣技術,該方法適用于電網有畸變及頻率有波動的電網測量,并提出了實現方案。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.
