Abstract

A TLM approach for the modelling of high and low frequency EMC problems in power systems C. Christopoulos*, V. Galdi^, L. Ippolito^ & A.

Abstract The EMC analysis of complex systems, as the electrified railway where trainset, power supply systems, telecommunication network and train detection and control systems are closely coupled by a variety of mechanisms, requires a detailed knowledge of the internal coupling relationships of the system components. The lack of information preclude any rigorous deterministic prediction of EMI and it requires a test campaigns in order to verify compliance with the limits fixed by international standards on EMI. Nevertheless, the difficulty in carrying out measurement in reproducible way and the cost of a possible system re
