摘要
在分析变压器空载合闸励磁涌流暂态过程的基础上,运用电磁暂态计算程序(EMTP/ATP)对核电厂辅助变压器的励磁涌流进行仿真研究。给出辅助变压器在不同合闸角度时励磁涌流和磁链的变化波形以及对应涌流中各次谐波的含量。最后,通过EMTP/ATP的仿真阐述采取选相合闸的方法来抑制励磁涌流的3种控制策略。
Based on the principle of the inrush current, this paper gives a EMTP simulation test system model for the energizing unload auxiliary transformer of nuclear power station. The inrush current in different flux linkage and energizing angle are simulated by setting the close and open time of the breakers. The harmonic of the inrush current is analyzed, which can give the site engineers useful instructions as well. Finally, the inrush current control strategy with EMTP/ATP simulation is discussed.
