Dimensioning DC Traction Substations with Realistic Traffic Scenarios

2017 IEEE Vehicle Power and Propulsion Conference (VPPC), 2017
The study of energy consumption is fundamental for railway systems in general and for DC electrified railway systems in particular. It plays an important role in order to design a proper dimensioning of traction Substations (SSs). DC electrical multi-train simulators allow studying a lot of electrical variables that are related to energy consumption ...

Analysis of the Energy Characteristics of the Traction Substation Rectifier

2021 IEEE 2nd KhPI Week on Advanced Technology (KhPIWeek), 2021
The analysis of the electromagnetic processes of a rectifier unit with a controlled pulse-width modulation with a booster rectifier is carried out. An expression for the power factor of a rectifier unit is obtained by an integral method for determining reactive power. It is shown that the adjustable pulse width modulation parameter has little effect on

Application of TSC in reactive compensation in traction substations

Proceedings 2000 International Workshop on Autonomous Decentralized System (Cat. No.00EX449), 2002
This paper presents the parameter design of components of thyristor switched capacitor (TSC) compensation with step-down transformer under the restriction of reactive power balance, and also mentions the pattern of TSC cooperated with fixed capacitor banks. The design and simulation is fully automated by the visual CVI.

Probability Distribution for the Feeder Current of Traction Substation

2009 Asia-Pacific Power and Energy Engineering Conference, 2009
Probability density function for feeder current of traction substation is fitted by using beta function through the theory of stochastic process and method of numerical analysis, and the distribution characteristic of feeder current is generalized and analyzed based on a great deal recorded feeder current data.

Heavy-duty rectifiers and their application to traction substations

Journal of the Institution of Electrical Engineers, 1931
As a result of the special problems associated with the supply of direct current to traction systems, as distinct from lighting and power systems, automatic substation technique has advanced in two widely diverging directions. Whereas modern substation practice in America is characterized by practice favours the adoption of mercury-arc rectifiers.

Influence of grounding wire configuration of traction substation

2019 11th Asia-Pacific International Conference on Lightning (APL), 2019
In this paper, the influence of grounding wire configuration of traction substation on observed transient overvoltage at some electric machines, those are diode rectifier, series reactor and so on, is experimentally measured. According to our previous experiences, a diode rectifier is the weakness against lightning and making the transient voltage ...
