| Popis: | This paper shows experimental results for three different methods used for a voltage synchronization to the three-phase grid. Tested methods are: traditional phase locked loop using Clarke and Park transformation (SRF-PLL), dual second-order generalized integrator phase locked loop (DSOGI-PLL) and sliding discrete Fourier transformation (sDFT). Experiments are carried out using controlled laboratory three phase power supply and show robustness of the methods to the noise, voltage distortion and sensitivity to grid frequency fluctuations. Finally, strong and weak aspects of the methods are discussed. |
