This document specifies requirements for the test and acceptance of simulation tools used for the design of DC electric traction power supply systems for urban rail guided mass transport systems, such as tramways, elevated and underground railways, mountain railways, trolleybus systems, and magnetically levitated systems which
use a contact line system. The validation process will be carried out for the 750 V DC voltage, and other voltages can be validated with the cross-acceptance.
This document focuses on the validation of the core simulation functions comprising the equations and functions
which calculate:
— the mechanical movement of trains and
— the load flow of the electrical traction power supply system.
