Abstract

DC traction power supply with 24-pulse rectifier is widely used in urban railway transit system. It is necessary to consider short circuit fault protection, because it is crucial for the design of equipments to meet requirements of safety and reliability. This paper presents a 24-pulse rectifier model, based on which the closeup and remote short circuit currents are obtained by programs. The calculation model presented is simple, efficient, and easy to get realized. The current profiles are then compared with that modeled in MATLAB/SIMULINK to prove their reliability. The result shows the accuracy of the model.
