| Abstract |
The railway system is destined to play a very important role in the future European transport system.
Many Institutions and Associations have established plans for its revitalisation. It is a matter of fact
that a significant increase in traffic is expected over the next few years. Railway infrastructure will
certainly have to be upgraded to support this traffic increase and to face the power consumption
increase and the excessive voltage drops. This upgrading may be realised by the introduction of new
technologies on the existing infrastructure, avoiding therefore the construction of new infrastructure.
This paper proposes a SVC as an interesting alternative to the construction of new lines and
substations. After HVB project, devoted to the choice of the adequate structure to ensure the voltage
regulation, in this second part of the project (HVB21) the chosen device (a SVC) has been designed in
detail, and a prototype has been built, installed and tested on the British and French railway systems.
This device has proved to be an interesting alternative to the construction of a new sub-station,
permitting a considerable improvement of the voltage profile. Special attention has been paid to the
design of a filter that not only eliminates the harmonics generated by the SVC, but it also improves the
overall distortion of the catenary voltage. Thus the main objective of this paper is to present the results
and conclusions obtained from the HVB project. |
