FAPS

Frequency Analysis of Power-supply Systems (FAPS)  is an advanced analysis tool for estimating the conducted harmonics generated on electrical systems and in-particular traction systems.

FAPS has been developed by TNEI as a joint development with Alstom Transport and SNCF. The objective is to significantly improve the harmonic modelling and frequency domain characterisation of electric rail networks.

It was the subject of a paper presented at RTS 2010 - Railway Traction Systems.
