基于J-A理论为船舶高压变压器建立一种非线性动态时域模型，并计及涡流损耗。该模型精确地反应了变压器铁芯的磁滞与饱和特性，可更准确地描述变压器的动态过程，可用于船舶变压器的设计及相关继电保护问题的研究。采用四阶龙格库塔算法求解非线性微分方程，使模型具有较高计算精度，建立了预充磁模型。变压器空载合闸仿真实验验证了模型的正确性。

A nonlinear time domain dynamic model was estab-lished based on the J-A theory for the ship high voltage trans-former , and the eddy current loss was also taken into account . This model accurately reflected the hysteresis and saturation characteristics of transformer core , and did well in describing the dynamic process of transformer , which can be used in ship transformer design and in the study of relay protection related . A fourth-order Runge-Kutta algorithm was used to solve non-linear differential equations so as to ensure the model has a high accuracy , and the pre-magnetizing model was estab-lished.The transformer no-load closing simulation results ver-ify the correctness of the transformer model .
