Analysis of the over-current phenomena while the EMU passing neutral section

Abstract

This paper analyzes the theory and characteristic of the over-current phenomena while the EMU passing neutral section and builds the mathematical expression of the flux linkage when several parallel transformers closing at the same time. It also builds the simulation model based on matlab/simulink and investigates the relationship between the number of transformers closed while the EMU passing neutral section and the value of the inrush current. © 2012 Springer-Verlag.
