| 摘 要： | 在实验基础上，提出了分层的铁心磁化建模规则，介绍了基于人工神经网络方法和分区分域测量的铁心磁滞模型。考虑了涡流模型及其参数计算方法。克服了传统模型主环只能应用极大环的信息，而次环只能通过主环线性压缩获得的一些缺点；克服了传统模型在电流互感器暂态计算中不考虑涡流效应的缺点。全面描述了电流互感器复合误差、暂态误差的计算方法。仿真与实验结果一致。

| Abstract: | Based on the experiment,Ascalar magnetizing model has been presented.A method based on the Aritifical Neural Network and measurement is used to describle the core's hysteresis,which considering the eddy current effect.The new model overcomes many defaults of the past magnetizing model.In this paper,the CT's complex error and transient error are introduced.The simulation results concide with the experiment. |
