Abstract

The invention relates to a system and method for simulating and analyzing the hysteresis characteristics of ferromagnetic materials under DC bias conditions. The method includes: generating a first-order gyration curve and displaying the generated first-order gyration curve; using the generated first-order The model parameter identification and hysteresis characteristic simulation analysis are carried out by using the slewing curve. The invention only needs the experimental data of the limit hysteresis loop, and the required experimental data is less, avoiding the complicated experimental design and measurement work and the resulting inefficiency and error, and effectively improving the ferromagnetic material generated under the DC bias condition. Accuracy of first-order slewing curves and Preisach hysteresis model simulation results. At the same time, high-order slewing curves can be predicted, making the simulation analysis of hysteresis characteristics more accurate and diverse.

Description

technical field [0001] The invention belongs to the research field of hysteresis characteristics of ferromagnetic materials, and in particular relates to a hysteresis characteristic simulation system and method of ferromagnetic materials under DC bias conditions. Background technique [0002] Hysteresis is one of the inherent important characteristics of magnetic materials. The hysteresis characteristics of different magnetic materials are mainly expressed by the shape of the hysteresis loop and the influencing parameters of the material. Magnetic materials exist in almost all electrical equipment, such as the iron core of transformers in power systems, inductance coils in generators, and electronic circuits. Due to hysteresis and eddy current phenomena inside ferromagnetic materials, when the internal magnetic field When it changes, iron loss will occur, which will affect the operating performance of electrical equipment. [0003] Power transformers in actual operation, du...
