An integrated methodology for 2 x 25 kV , 50 Hz traction system calculation
نویسنده
چکیده
The paper describes an integrated calculation methodology which, by simulating railway traffic, allows analysis of the performance of 2x25 kV 50 Hz electric traction systems. This methodology performs a multiconductor electrical analysis of the traction circuit utilising ATP-EMTP software (Alternative Transient Program-Electromagnetic Transient Program) and therefore additionally allows calculation of electromagnetic transients and all possible failure regimes. The analyses presented refer to the application of the methodology in question to the study of a high speed railway line section in steady-state operation, with particular emphasis on the electrical and energetic effects of train regenerative braking.

Protection setting in 2x25 kV 50 Hz railway traction systems by digital simulation
In this paper, after a short description of the problems related to the detection of short circuits in 2x25 kV 50 Hz traction systems, a methodology for the choice of the operating area of the relay for protections based on the comparison between a measured line impedance and a fixed minimum impedance is presented. The proposed methodology has been realized through the development of a procedur...
متن کاملPower Quality Analysis in Electric Traction System with Three-phase Induction Motors
Three-phase induction motors are widely used in electric traction systems. Impacts of the traction vehicle equipped by three-phase induction motors on power quality are much different from the impacts of vehicles with DC traction motors. In this paper, the effects of the traction vehicle operation with threephase induction motors on power quality in 110 kV transmission network are investigated....
متن کاملSteady State and Transient Short Circuit Analysis of 2x25 kV High Speed Railways
In the paper, a detailed model for the short circuit analysis of the AC 2x25 kV-50 Hz traction system has been derived and implemented. Two different methods have been used: the time domain and frequency domain approaches. The two approaches are discussed and numerical applications are reported. In particular, in order to assess the feasibility of both the two methodologies, the results have be...
متن کاملSimplified model and submodule capacitor voltage balancing of single-phase AC/AC modular multilevel converter for railway traction purpose
A single-phase AC/AC modular multilevel converter (MMC) can interact directly with 25 kV railway grid without a bulky 50 Hz step-down transformer. This brings in great savings in size and cost. Submodule (SM) voltage balancing of this kind of MMCs remains a major technique issue. This study proposes a voltage-balancing solution for this scenario which consists of intraand inter-arm voltage bala...
متن کاملMeasurements on 25 kV Traction Power Supply Systems
At the moment 25 kV traction power supply systems are being introduced in the Netherlands. Currently in the Netherlands a 1500 V DC system is used, however due to increasing energy demands this system is no longer sufficient. For the high-speed lines and heavy freight lines, which are under construction, the 2x25 kV AC system has been chosen. Introduction of this new technology leads to differe...
