Mitigation of NSC and Alleviate of Magnetic Inrush Currents in Indian Traction System

Gopi Krishna Allaboyena

Abstract: The running of electrified railways causes many problems in the electric utility systems as the traction is a very duty dynamic load. This causes many power quality problems in the system resulting in malfunction of protective relays, circuit breakers, increment in transformer losses etc This paper focuses on the mitigation of Negative Sequence Currents (NSC) and how the magnetic inrush currents affect the system. The NSC has been compensated indirectly with reference of harmonics. The corresponding results have been discussed and published using MATLAB/Simulink 2014 software.

Keywords: Negative Sequence Currents NSC, harmonics, transformers, induction machines, power convertors
