Cost-effective upgrade of the Dutch traction power network:Moving to Bi-directional and controllable 3 kV DC substations for improved performance

Traction power networks can significantly influence a country's national grid due to their significant power consumption and numerous coupling points. To modernise the ageing Dutch traction power networks and enhance their impact on the utility grid, this study explores practical and cost-effective approaches for upgrading existing 1.5 kV DC traction substations (TS) in the Netherlands into 3 kV bi-directional DC TS. After evaluating the benefits of a 3 kV bi-directional DC, two novel topologies are proposed that re-use the existing substation's components and reduce the need for higher invest... Mehr ...
