Abstract |
This paper carries out the power analysis in case of regenerative power generation in the AC power supply system, which is using the scott transformer. In particular, the three phase power characteristics of the primary side are analyzed numerically according to the single phase power characteristics of the secondary side of the transformer. More specifically, the power characteristics of the three-phase side are presented by classifying the cases according to the conditions of accelerated and regenerative operation of the secondary side of the transformer. In addition, the power characteristics presented in this paper are verified by comparing the values analyzed numerically with those measured at the substation. |
