An Example of DC Power Supply System Studies

for Rapid Transit System and the Introduction

of Energy-saving Technology

Abstract

This article mainly focuses on thoroughly analyzing the issues that must be considered in DC
system study when designing power supply systems for the Taipei MRT. It will explain the required
design standards, and the purpose and goals of the process. Using the DC power supply system of
the Xinzhuang-Luzhou and Zhonghe lines as an example, concrete simulated analytical results from
the case are interpreted in detail. This paper also briefly introduces and compares various kinds of
energy-saving technologies applicable to rapid transit systems, with the expectation that these new
power supply technologies will be brought into use in the future.

Key Words：traction load flow study, DC short circuit study, stray current analysis, rail potential
analysis，energy saving
