| 摘要: |
| 为分析移相变压器不对称对12脉波整流系统的影响，建立了原边为三角形联结的自耦变压器的全解耦模型。通过分析自耦变压器的耦合电路图，给出了支路电压、支路电流、节点电压和节点电流的关系，推导出可用于描述自耦变压器绕组联结特点、电气参数等信息的节点导纳矩阵；应用该矩阵，建立了三角形联结自耦变压器的全解耦模型，并给出了模型参数与变压器实际参数的关系。仿真和实验结果验证了模型在模拟自耦变压器不对称时的有效性。 |

| Abstract: |
| A completely decoupled model of delta-connected autotransformer is built to analyze the effect of the asymmetry of phase shift transformer on the 12-pulse rectifier. By analyzing the coupling circuit of autotransformer，the relationships among branch voltage，branch current，node voltage and node current are obtained and a node admittance matrix is derived for describing the information of winding connection pattern，electrical parameters and so on. Based on the matrix，a completely decoupled model of delta-connected autotransformer is built and the relationship between model parameters and practical parameters is obtained. Simulative and experimental results verify the effectiveness of the model in simulating the asymmetry of delta-connected autotransformer. |
