摘要

通过有载合闸变压器模型

分析了变压器有载合闸过程中由于副边突然短路导致主保护动作时电流和磁通的暂态过程

并对变压器铁心内的剩磁作了定性的分析。

Abstract

A reasonable transfomer model for analyzing the transient process of closing with load is proposed. At the same time

a new algorithm is put forward to explain the fault current and transient flux when secondary winding is broken down during closing with load. The residual flux in iron core is analyzed too.
