摘　　要：船舶综合电力推进系统移相变压器空载合闸时产生的励磁涌流容易引起船舶电网综合保护装置误动和开关损坏。为研究励磁涌流的抑制方法,首先在移相变压器空载合闸时励磁涌流数学分析的基础上,分析不同励磁涌流抑制方法的优缺点,提出适合船舶电网的预充磁方法。然后在Matlab/Simulink中建立基于延边三角形接法原理的移相变压器模型,通过仿真验证预充磁方法抑制移相变压器励磁涌流的有效性并研究相关问题。The excitation inrush current generated when the phase-shifting transformer of the marine integrated electric propulsion system is switched on without load is easy to cause misoperation and switch damage of marine integrated power grid protection device.In order to study the suppression method of excitation inrush current,this paper firstly compares the advantages and disadvantages of different suppression methods of excitation inrush current,and proposes a pre-excitation method suitable for ship power grid on the mathematic analyses.Then,this paper builds the model of phase-shifting transformer with prolong delta winding connection in Matlab/Simulink.The simulation results show that the pre-excitation method on excitation inrush current suppression is effective.
