Harmonic reference currents balancing method for delta‐connected static synchronous compensator.

A static synchronous compensator (STATCOM) with a delta configuration is able to compensate for reactive currents, unbalanced currents and harmonic currents in a three‐phase three‐wire system. A method is proposed for balancing the harmonic currents among three phases of the STATCOM without affecting line harmonic currents injecting into the grid. The rating of the STATCOM can be lower because the maximum phase current is reduced. Simulation and experimental results are provided to show the effectiveness of the proposed method.
