摘要

电力变压器设计需要对高磁导率晶粒取向电工钢层压铁芯的损耗和磁滞特性进行建模。这项工作预测了三种变压器级钢在轧制方向上的磁损失和磁滞行为，磁通量密度高达1.9 T，频率高达300 Hz。通过对正弦同心磁滞回线的统计损耗分离得到的材料特性参数用于磁滞模型并控制动态场行为。将模型的损耗与Epstein框架对每个钢规的测量数据进行了比较和验证。

Coupled statistical and dynamic loss prediction of high-permeability grain-oriented electrical steel

Power transformer design requires to model the loss and hysteresis behavior of the laminated steel core, constructed out of high-permeability grain-oriented electrical steel. This work predicts the magnetic loss and hysteresis behavior in the rolling direction of three transformer grade steels, for magnetic flux densities up to and including 1.9 T, and frequencies up to and including 300 Hz. Material characterization parameters for the excess loss, obtained by statistical loss separation for sinusoidal concentric hysteresis loops, are applied in a hysteresis model and govern the dynamic field behavior. The modeled loss is compared and verified with measurement data obtained by an Epstein frame for each steel gauge.
