“…The actual structural components must be reasonably simplified, but the electric and magnetic anisotropies of the laminations should be taken into account. The method used in this paper is based on a simple model to deal with standard iron loss and additional iron loss [24][25][26].…”

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 grainoriented 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 threedimensional harmonic magnetisation. Field and loss comparison between measurement and simulation verifies the validation of the proposed modelling method.

This paper highlights two important aspects of the electromagnetic field modeling and simulation when used for industrial applications, namely the application based benchmarking activities and the magnetic material modeling. It emphasizes the relationship between the two, and briefly reviews the recent progress in extending the TEAM (Testing Electromagnetic Analysis Methods) Problem 21 Family (P21) and the related modeling results, and proposes a new benchmarking project which includes the upgraded benchmark models that can handle extreme excitations, i.e. current sources with a DC bias, as well as multiple harmonics.

“…The shielding component, laminated by a number of pieces of silicon steel sheets with high magnetic permeability, is often used for clamping the ends of windings and oil tank, where the leakage magnetic field is quite sizeable [9]- [11]. It is imperative to evaluate the stray loss of the structural parts for local overheating prediction and optimal design of large power transformers.…”

To investigate the stray loss in magnetic shielding components immersed in the 3-D AC-DC hybrid leakage magnetic field, a modified method is presented with the variation of the eddy current loss inside the coil due to the change of the leakage magnetic field taken into account. In addition, a new loss separation model is proposed to estimate the standard iron loss of the grain-oriented (GO) silicon steel sheet under AC-DC hybrid excitations. Furthermore, the material properties were appropriately treated based on the simplified model of laminated magnetic shielding for efficient numerical calculation. The comparison of field distribution and loss results obtained by experiment and calculation respectively was made, which shows good consistency and thus verifies the effectiveness of the proposed method in this paper. Meanwhile, the stray loss and additional loss in magnetic shielding are analyzed in detail to evaluate the potential threat of AC-DC hybrid excitations on the local overheating of the structural parts in HVDC transformers.
