Abstract

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.
