DC operating power connection and rated voltage selection for transit substation

Wang Kaikang;  
In view of the problem that the DC operation for power connection and the bus rated voltage design standard in urban rail transit substation are not uniform, this paper analyzes different schemes, and recommends: A single bus connection should be used for DC operation power supply in station substations, the DC operation power of main substation should use single bus section connection, the rated voltage of the bus line of DC operating power should choose DC110V voltage level as the priority. The recommendation scheme has the advantages of meeting the specification requirements, simple system structure, less engineering investment and convenient engineering implementation.
