Improved DSOGI-PLL for synchronizing frequency detection of mine power grid voltage

Improved DSOGI-PLL for synchronizing frequency detection of mine power grid voltage

In view of problems that there are frequency and phase errors in extracting voltage synchronization signals of DSOGI-PLL with multiple harmonics or DC bias in mine grid, an improved DSOGI-PLL was proposed to improve DSOGI-PLL from three aspects: frequency regulation, DC bias and harmonic detection.F...
