Motivation:
|
|
|
|
|
|
Current limitation
High currents are a problem for on-board power electronics.
Reduction of traction losses is just a side effect. |
|
|
|
|
|
|
|
|
Benefits (other than environmental): medium |
|
|
|
|
|
Current limitation
Excessively high currents have a negative effect on traction power
electronics. |
|
|
|
|
|
|
|
|
Barriers: medium |
|
|
|
|
|
Retrofit of old vehicles is not feasible. |

Environmental criteria
|
|
|
|
|
|
|
|
|
|
|
Impacts on energy efficiency:
|
|
|
|
|
Energy efficiency potential for single vehicle: < 2% |
|
|
|
|
Energy efficiency potential throughout fleet: < 1% |
|
|
|
|
|
No data on saving effect are available. Given that catenary losses account for about 10% of the energy drawn from substations, and the fact that the control tool regulates the current only within a small range, the overall saving potential will be less than 2%. |
|
|
|
|
|
|
|
|
Other environmental impacts: neutral |

Economic criteria
|
|
|
|
|
|
|
|
|
|
|
Vehicle - fix costs: low |
|
|
|
|
|
As part of new vehicles, the control tool does virtually not increase the vehicle price. |
|
|
|
|
|
|
|
|
Vehicle - running costs: minor reduction |
|

|
|
|

|
|
|
|
Scale effects: none |
|
|
|
|
|
Being a standard in new electric stock already, additional scale effects are not to be expected. |
|
|
|
|
|
|
|
|
Amortisation: < 1 year |

|
Overall potential: interesting |
|
|
|
|
Time horizon: short-term |
|
|
|
|
|
A control mechanism for power intake has become a standard in new electric stock. The saving potential is moderate. Since a retrofit of old stock is not possible, the diffusion of the technology does not depend on any additional efforts on the part of railways. |
