Grid synchronization and symmetrical components extraction with PLL algorithm for grid connected power electronic converters - a review

Abstract: Abstract. In this paper, a review of Phase Locked Loop (PLL) algorithms and symmetrical component extraction methods intended for grid-connected power electronic converters are presented. Proposed classification is based on voltage representation in three coordinates: natural (abc), stationary (αβ) and rotating coordinates (dq). The three selected algorithms are described in details: Dual Second Order Generalized Integrator (DSOGI-PLL), Dual Virtual Flux -both in stationary coordinates. The third one, in rotat… Show more

The advantage of this power compensation method is that the use of NS current components is not required as they are often very small and large errors may be produced, when compared with using of the PS current components.…”
