scope:

This guide provides a description of the data, techniques, and procedures used in modeling and analysis of rail transit traction power systems.

Purpose

This guide provides methods and terminology for rail transit traction power system modeling.

Applicability

This guide is intended for application by engineers involved in the design and specification of new traction power systems, as well as the technical evaluation of existing traction power systems in response to redefinition of operating parameters (e.g., increase in service).

DC versus ac traction power systems

This guide is intended to apply primarily to dc traction power systems. However, many of the techniques can be applied to ac traction power system analysis.
