摘　　要：针对现有变压器仿真模型电感参数计算存在的问题,提出了一种从磁路计算变压器模型参数的方法。该方法从变压器的基本耦合磁路出发,分别计算变压器的互感和漏感,并且在计算漏感矩阵的时候,考虑了纵向漏磁通和横向漏磁通的影响,使得应用此方法得到的电感参数更加准确。为了验证磁路计算法的正确性,将一台模拟变压器的内部故障仿真试验数据与动模试验数据进行了比较,结果表明提出的磁路计算法是正确的。For the problems in the inductance calculation of transformer simulation model , this paper presents a calculation method with transformer magnetic circuit. This method calculates the mutual inductance and leakage inductance respectively. When calculating the leakage inductance, the effect of vertical leakage flux and horizontal leakage flux have been considered, which makes the calculating result are more correct. In order to prove the validity of this method, the data of simulation test and dynamic analog test have been compared. The results prove that the method of magnetic circuit calculation is accurate.
