摘　　要：本文针对电力变压器漏磁场引起的杂散损耗问题,基于TEAM PROBLEM21基准族中的P21~C-M1实验模型,考察了交直流混合激励条件下,导磁钢板及取向电工钢叠片内的磁通分布及杂散损耗。通过计算杂散损耗的传统方法,从交直流混合激励和交流单独激励下的负载总损耗中分别分离出磁屏蔽的杂散损耗值,从而得到直流分量对磁屏蔽损耗的影响规律,即直流电流分量引起了磁屏蔽杂散损耗的增加。通过精细建模仿真计算出磁屏蔽的杂散损耗,与测量结果进行对比,验证了本文方法的有效性与正确性。The purpose of this paper is to study stray loss caused by leakage magnetic field of power transformers.Magnetic flux distribution and stray loss of magnetic plate and oriented electrical steel lamination under AC-DC hybrid excitation are studied based on the experimental model of P21 C-M1 in TEAM Problem 21 benchmark family.By means of the traditional method of calculating the stray loss,the stray loss of magnetic shielding value is separated from the total load loss under AC-DC hybrid excitation and AC excitation in separate,resulting in the effect of DC component on the stray loss of magnetic shielding.The result of comparison of experimental results with the simulation results that are calculated by fine modeling and simulation shows the correctness and efficiency of this method.
