Design of electric catenary system on open track

摘要

The present invention relates to an electric railway system, and more particularly, to the tramway design of the earthwork section of the electric railway system.;Conventionally, in the design of tram lines in earthworks sections of electric railway systems, the estimated loads of tram line sections are selected, the load current is calculated, and the electric lines are selected by selecting a cable having approximately tens of percent margin by comparing it with the allowable current for each wire standard. The furnace was designed. However, as the electric vehicle operation schedule changes, the load input amount is changed. At this time, the power supply simulation according to the change of the load input should be performed. As in the related art, the load current is calculated by a simple calculation method, so that the optimum earthwork It is not possible to design section streetcars.;According to the present invention, when designing a catenary line for an earthwork section of an electric railway system, information about conductors required for a corresponding section is read from a database, an impedance for each conductor is calculated, and an impedance input by an operator is compared to be within a predetermined allowable range. The purpose was to select the conductor and design the optimal tramline system equipment for earthworks section.
