A grid frequency estimation method based on moving average filter half-tangent phase-locked loop

open access: yesDiance yu yibiao
This paper proposes a half-tangent phase-locked loop (HTan-PLL) with a moving average filter (MAF) for estimating grid frequency. The proposed PLL utilizes a half-tangent phase detector (PD) and introduces MAF into the phase-locked loop to address ...
