摘要

铁磁元件是电力系统的主要设备构成

其电磁特性影响到系统的稳态运行和暂态保护控制。J-A模型是描述铁磁材料具有磁滞现象的主流磁化模型

既可反映宏观磁化现象

又能计算微观能量损耗变化

因而得以广泛应用。文中综述了J-A理论的基本体系、矢量化研究及J-A模型的参数辨识研究

对其磁耦和、钉扎效应、畴壁运动等关键点进行了阐释;接着

以电力系统中的变压器、互感器为应用对象

综述了J-A模型用于电力元件的需求分析;最后从J-A模型理论本身、计算精度优化、动态时频特征匹配几个方面展望了J-A理论研究的改进趋向。

Abstract

The ferromagnetic components are the main components of the power system

which electromagnetic characteristics affect the steady operation and transient protection control of the system.The J-A model is the main model describing hysteresis of ferromagnetic materials.It can not only reflect macroscopic magnetization

but also calculate the change of micro energy loss

and has been widely used by scholars.This paper reviews the theoretical system of JA

the research of vectorization

and the parameter identification of J-A model.In particular

this paper addresses the key points of J-A

such as the model of magnetic coupling

pinning effect and domain wall motion.Then

taking the transformer and mutual inductor in the power system as the application objects

this paper summarizes the demand analysis of the J-A model for power components.Finally

the improvement of J-A research is prospected from JA theory itself

accuracy optimization and dynamic time frequency feature matching

etc.
