摘要针对电力变压器发生直流偏磁时,产生的励磁电流畸变、谐波及损耗增大问题,本文从直流偏磁产生的机理出发,基于J-A模型理论,从能量平衡原理的角度,利用该模型对无直流偏磁及直流偏磁下的变压器铁心励磁电流及磁滞回线进行仿真模拟及实验研究。重点讨论了J-A磁滞模型的原理,参数识别。仿真及实验结果表明,该模型能够很好的描述直流偏磁下电力变压器铁心励磁电流和磁滞回线的波形特征,为研究直流偏磁下电力变压器的性能提供了有效的方法。

Abstract：Aimed at issues that the resulting excitation current distort, harmonic and loss increase when DC magnetic bias occur on power transformers, this paper started from the production mechanism of DC magnetic bias, based on theory of J-A model, from the view of energy balance principle, current excitation current and hysteresis loop of transformer core without DC magnetic bias and under DC magnetic bias were simulated and experiment researched by using the model. The discussion mainly focused on principle of J-A model parameter and parameter identification. Simulation and experiment results show that the model can well describe waveform characteristics of excitation current and hysteresis loop of the transformer core under DC magnetic bias, it had provide an effective approach for the study of power transformers performance under DC magnetic bias.

Key words： DC magnetic bias power transformer excitation current J-A hysteresis model
