Özet:

 

Modular multilevel converters  MMCs  are characterized by modularization and multielectric equality, and   the application of this structure to a high-voltage large-capacity static synchronous compensator  STATCOM  shows   good potential. In this paper, a modified instantaneous symmetrical component method is proposed for positive- and   negative-sequence decomposition, i.e. the critical part of the control device, which can accurately detect the instantaneous   value of each sequence component in three-phase asymmetrical phasors in real time. Then, based on this method, the   paper proposes a control method for MMC-based STATCOMs that solves the problems of multi-DC  direct current    voltage balance, grid-connected current control, and circulation suppression. Finally, the proposed detection and control   methods are verified by performing simulations and experiments. The results show that the proposed method can quickly   and accurately detect the positive- and negative-sequence reactive component that should be compensated by the device,   thus realizing real-time reactive compensation for MMC-based STATCOMs.
