Traction Power Substation Load Analysis with Various Train Operating Styles and Substation Fault Modes

Modeling for Power Supply Substation in Maglev Train System

Since a power supply substation of the magnetic levitation train system includes an inverter which is necessary to change the frequency of power, it has a different characteristic comparing to any other railway system. Nowadays, a study is undergoing to determine rating of facilities constituting a power supply system and modeling that system. This paper proposes an analysis model for the power...

Power System and Substation Automation

Automation is “the application of machines to tasks once performed by human beings, or increasingly, to tasks that would otherwise be impossible”, Encyclopaedia Britannica [1]. The term automation itself was coined in the 1940s at the Ford Motor Company. The idea of automating processes and systems started many years earlier than this as part of the agricultural and industrial revolutions of th...

A Traction Three-Phase to Single-Phase Cascade Converter Substation in an Advanced Traction Power Supply System

The advanced traction power supply system (ATPSS) is a new directional development for traction power supply systems, which can totally remove the neutral sections and effectively promote power quality. However, the existing converters suffer from small substation capacity. In this paper, a new configuration based on a three-level neutral point clamped (3L-NPC) three-phase to single-phase casca...

Artificial Neural Network-based Distribution Substation and Feeder Load Forecast

Artificial Neural Networks (ANNs) have been successfully applied to the problem of forecasting future load values, especially in the short term framework (a few minutes to a few hours ahead). Traditional analytical models have shown difficulties when dealing with (i) the highly variable demand curve shapes, (ii) some independent variables that exhibit random behaviour, and (iii) the identificat...
