VSC Based D-STATCOM with Selective Harmonic Elimination

open access: yes2007 IEEE Industry Applications Annual Meeting, 2007
This paper describes the design, implementation, and performance of a medium-size distribution-type static synchronous compensator (D-STATCOM) with the simplest two-level three-leg voltage-source converter (VSC) topology. Reactive-power control is achieved by phase-shift-angle control, and VSC harmonics are eliminated by selective harmonic elimination ...
