Abstract：A new modular multilevel converter is proposed for static synchronous compensator (STATCOM), which is hereafter called M-STATCOM. The new shunt comprehensive compensator, features with the advantages such as high modularity, availability, low generation of harmonics, etc. is suitable for medium- or high-voltage utility grid without line-frequency transformers. M-STATCOM can not only be controlled in static var generating condition for reactive power compensation purpose, but also be suitable for the comprehensive mitigation of all the power quality problems under the three-phase unbalanced power systems. The structural characteristics and operating principles of M-STATCOM for both static var generating condition and comprehension compensating condition are analyzed in detail. Moreover two corresponding control schemes are proposed. The effectiveness of the proposed control strategy and feasibility of analysis is validated by the experimental results.
