Abstract
At development of common concept of current collection for three-phase traction power supply system there is the need to select and substantiate main design parameters of catenary suspension. For this purpose, the authors have carried out analytical calculations and developed a numerical mathematical model that allows assessing catenary statics and it’s dynamics in interaction with current collector. On the basis of results of modeling, the authors have substantiated and selected all the required parameters. In particular, they have determined the permissible speed of trains and maximal length of catenary spans.
