The magnetic property measurementfor grain oriented (GO) silicon steel sheet under non-sinusoidal excitations (DC bias and harmonic) were conducted based on the experimental platform. Based on the Preisach model, the static hysteresis and loss properties were accurately simulated. Furthermore, an improved loss model was proposed by adjusting the statistical parameter of abnormal loss, which depends on the characteristic quantities of DC bias or harmonic excitations. The simulated dynamic hysteresis loops and iron losses under different non-sinusoidal conditions were compared with the measured ones, and thus the accuracy and generality of the improved model proposed in this paper were verified. In addition, the influences of the harmonic and DC-biasing quantities upon the total losses is investigated.

非正弦励磁下GO硅钢片动态磁滞和损耗特性的仿真方法


基于该实验平台，对非正弦激励（直流偏压和谐波）下取向硅钢片的磁性能进行了测量。基于Preisach模型，准确模拟了静态磁滞和损耗特性。此外，通过调整异常损耗的统计参数，提出了一种改进的损耗模型，该参数取决于直流偏置或谐波激励的特征量。将不同非正弦工况下的模拟动态磁滞回线和铁损与实测结果进行比较，验证了本文提出的改进模型的准确性和通用性。此外，还研究了谐波和直流偏置量对总损耗的影响。
