三相三柱变压器暂态仿真

Transient Simulation of Three-phase and Three-leg Transformer

以三相三柱式变压器铁心磁路为基础 ,建立了变压器的暂态模型。分析了模型参数和变压器实验值的关系 ,可利用变压器的实验值及几何参数确定模型参数。

Based on the magnetic circuit of the three leg core transformer, a trnasformer transient model are given. The relations between the model parameters and the test values of the transformer are investigated. With the test values and the geometry parameters of the transformer, the model parameters can be determined. The model can be used for transient simulation of transformer’s fault and inrush current.
