Scope

This European Standard, part 2 of EN 50388 is linked to prEN 50388-1 which describes the general items on technical criteria for the coordination between power supply and rolling stock to achieve interoperability
This part 2 establishes the acceptance criteria according to prEN 50388-1:2017, 10.4 step 7 for compatibility between traction units and power supply, in relation to:
- co-ordination between controlled elements and between them and resonances in the electrical infrastructure in order to achieve network system stability;
- co-ordination of harmonic behaviour with respect of excitation of electrical resonances.
The following electric traction systems are within scope:
- railways;
- guided mass transport systems that are integrated with railways;
- material transport systems that are integrated with railways.
Public three phase grid is out of scope. Railway dedicated grid is included.
This European Standard is applied in accordance with the requirements in prEN 50388-1:2017, Clause 10. It does not apply retrospectively to rolling stock already in service.
It is the aim of this part 2 to support acceptance of new elements (rolling stock or infrastructure) by specifying precise requirements and methods for demonstration of compliance. However, it is still admissible to use the process as defined in part 1 instead. The process of part 1 shall be applied if the case studied is not covered by part 2.
This version of the standard only applies to AC systems. Later versions may include similar effects in DC networks in addition (see Annex D).
Main phenomena identified and treated in this standard are:
- electrical resonance stability;
- low frequency stability;
- overvoltages caused by harmonics.
The interaction with signalling (including track circuits) is not dealt with in this standard.
