摘要

采用计算机仿真模拟方法对电力系统中影响电流互感器剩磁的因素及其发生规律进行了系统的研究。应用电磁暂态仿真程序ATP建立电流互感器模型，对短路电流开断时间、一次短路电流及其非周期分量、一次回路时间常数以及二次负载的功率因数及阻抗值等不同影响因素作用下剩磁的变化进行了系统的计算分析，获得了剩磁的发生规律，为抑制剩磁的产生提供了基础理论依据。

Abstract

Systematic studies of the influences of several factors on the residual flux and the characteristics of residual flux occurrence in current transformers are conducted by computer simulations. The current transformer model is established using the electro-magnetic transient program ATP. Detailed simulation studies are performed for the resultant residual flux under the impact of several factors， including short-circuit current breaking time， short-circuit current and its aperiodic component， primary side time constant， power factor and impedance of load at the secondary-side. The characteristics of residual flux occurrence obtained by this work provide theoretical basis for inhibiting the residual flux.
