Abstract: Following express train electric railways connected into the power grid in large scale, in order to study the power quality change characteristics at system side after express train connected into grid, this paper built up the simulation model of CRH2 type express train tracking power supply system in PSCAD/EMTDC software. Verification was carried out from different angles for the built simulation model of express train. On the basis of matching analysis of express train actual operation working condition, taking Beijing-Shanghai express train Nanjing section for example, this paper analyzed the power quality change characteristics of express train actual operation at system side under different operation working conditions, which provides reasonable suggestions for express train power quality monitoring analysis and treatment and actual operation control optimization.
Key words: express train; power quality analysis; PSCAD/EMTDC software; tracking power supply system; modeling simulation
