Abstract:This paper discussed the connections and distinctions of three kinds of traction power supply systems of universal speed railway, high-speed railway and metro. First, these three kinds of traction power supply systems were analyzed from the perspectives of power supply, transformers, traction substation connection and protective configuration. And then, key technology developments of traction power supply systems were summarized as well as the connections and distinctions among the three kinds of traction power supply systems. Finally, the trend of traction power supply technology was presented.
Key words: traction power supply system; rail transit; universal speed railway; high-speed railway; the subway metro; transformer
