Abstract :
Circulation of direct current in transformer windings can cause significant transformer saturation and harmonic generation. This problem may be experienced by static VAr compensators with an anti-parallel thyristor arrangement. This paper presents a technique to analyze the harmonic distortions caused by transformer saturation with direct current offset. The technique is used to investigate the harmonic generation from the transformer of a static VAr compensator to be installed in the BC Hydro system
