The advantageous use of static converters for 50 Hz traction power supply, which is technically, operationally and economically undisputable, appears to be attractive also under fi nancial aspects. First concrete applications are offered by the newly structured Trans European Transport Network in which several thousand kilometres of railway track are planned to be upgraded or newly built by 2030.

Nowadays, powerful DC trains run in interconnected overhead line contact systems. Converting them to AC operation in the conventional way, i.e. using phase-changing substations or even transformers, means new disadvantages to both the trains and the 3AC operators. Among these disad-vantages are power peaks that occur when catching up on speed losses after idling runs in phase separation sections. Static converters now again permit an interconnection of the line systems which allows a conversion to be re-assessed. Source

In their efforts to further improve energy effi ciency Chinese Railways are confronted with a strong verdict by operators of high voltage grids against feeding back of regenerative braking power. A technical solution to this will be using in traction substations, which will provide phase-synchronized voltages, thus allowing catenary to be coupled through. So regenerated braking energy can be distributed over longer distances. Fringe benefi ts can be expected as regards total investment and operational costs. Source

The energy turnaround has been intensively discussed in Germany since 2010. Thereby, the development potentials of hydropower do not occur apparently as with other renewable energies. In addition to site-specific conditions, the deployment of new technology primarily plays a role as in the case of economically operating generators of the latest generation. Source
