- Abstract
- The hybrid transformer is developed for not only boosting voltage but also removing harmonic in 2009. So far researches for hybrid transformer have been done about study of only operation characteristic or analysis by using simulation of grid mainly. In this paper, we modeled the hybrid transformer and analyze its effect in real power grid. For verifying reduction of harmonic, we modeled the grid-connected photovoltaic generation system, which is typical eco-friendly generator, as a harmonic source. Hybrid transformer, a transformer with Zig-Zag winding, is used in analyzing the phase change between input and output voltage when the winding direction of the transformer is altered. Also, the harmonic content of source is analyzed depending on the existence of hybrid transformer. As a result, it can be seen that the hybrid transformer reduces the harmonic content by 9%.
