基于TEAM problem 21基准模型，提出并验证了一种预测真实的工况下杂散磁场损耗的建模方法，系统研究了谐波激励对高压直流换流变压器屏蔽结构件杂散磁场损耗的影响。在实验测量和数值模拟的基础上，提出了一种改进的方法来确定磁性和非磁性部件的杂散场损耗。建立了取向硅钢片磁性能和损耗特性的实验平台，对取向硅钢片谐波磁化下的损耗模型进行了参数辨识和验证。同时，通过对材料特性的特殊处理，得到了垂直磁通穿透引起的附加铁损，并对其进行了分析，以观察其对三维谐波磁化下杂散场损耗的贡献。实测和仿真的场和损耗比较验证了所提出建模方法的有效性。
On the basis of the TEAM problem 21 benchmark model, a modelling method to predict stray‐field loss under real working conditions is presented and validated to investigate the influence of harmonic excitation on stray‐field loss of shielding structural components of converter transformers in high‐voltage direct current systematically. An improved method is adapted to determine stray‐field loss of magnetic and non‐magnetic component based on the experimental measurement and numerical simulation. An experimental platform is established to measure magnetic properties and loss characteristics of the grain‐oriented silicon steel sheets, aiming at parameter identification and verification of the loss modelling applicable for laminated sheets under harmonic magnetisation. Meanwhile, the additional iron loss caused by perpendicular flux penetration is obtained by special treatment of material properties and analysed to observe its contribution to the stray‐field loss under three‐dimensional harmonic magnetisation. Field and loss comparison between measurement and simulation verifies the validation of the proposed modelling method.
