Description
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.
NOTE 1 This document provides only the requirements for demonstration of the algorithms and calculations of core functions. The use of a validated simulation tool in accordance with this document does not in itself, demonstrate good practice in electric traction power supply system design, neither does it guarantee that the simulation models and data for infrastructure or trains used in the tool are correct for a given application. The choice and application of any models and data, of individual system components, in a design is therefore subject to additional verification processes and not in the scope of this document. Competent development of design models and full understanding of the limits of design tools remain requirements in any system design. This document does not reduce any element of the need for competent designers to lead the design process.
This document also specifies procedures for the modification of simulation tools, in particular the limits of applicability of acceptance when tools are modified. These procedures focus on determining whether the core functions of the simulation model are modified.
Because the purpose of this standard deals with the verification of the core functionality, the test case described in this document does not represent an existing network.
NOTE 2 Additionally, the application of this document ensures that the output data of different simulation tools are consistent and verifiable when they are using the same set of input data as given in this document.
This document excludes complex models with active components such as controlled rectifiers and inverters.
This document does not mandate the use of a particular simulation tool in order to validate the design of an electric traction power supply system.
This document does not deal with validation of simulation tools by measurement.
The document is not applicable to the validation of simulation tools with respect to:
- short circuit studies;
- electrical safety studies (e.g. rail potential);
- harmonic studies;
- studies of transient phenomena; and
- electromagnetic compatibility studies over a wide frequency spectrum.
