在对变压器励磁涌流的仿真中，变压器铁芯的非线性磁化特性必须加以考虑。本文运用人工神经网络模拟主磁滞回环，以及用线性变化的位移来生成局部磁滞回线的方法，建立铁芯动态非线性磁化过程的计算模型。在此基础上对变压器的励磁涌流进行了仿真，收到了较好的效果。
In the simulation of transformer magnetizing inrush, the nonlinear magnetizing characteristics of transformer core must be considered. In this paper, artificial neural network is used to simulate the main hysteresis loop and the method of generating local hysteresis loop with linearly varying displacement, and the calculation model of the dynamic nonlinear magnetization of the core is established. On this basis, the simulation of the magnetizing inrush of the transformer has been carried out, and the better result has been received.
