A Nonlinear Model for Marine High-Voltage Transformer
Ling Jie Zhang, Cai Qin Sun, Jian Bo Sun · Applied Mechanics and Materials · 2014
A nonlinear model for the marine high-voltage transformer is established which based on the J-A theory , considered the eddy current loss. This model accurately reflects the nonlinear characteristics of the transformer, and does well in describing the dynamic process, it is propitious to design the ship transformer and the study of relay protection. A fourth-order Runge-Kutta algorithm is used to solve the nonlinear differential equations to ensure the model has a high accuracy, and the pre-magnetizing model is also established. At last, through the transformer no-load closing simulation results verified the correctness of the model.
