Investigation of paralleling Bipole II and the future Bipole III in Nelson river HVDC system
Manitoba Hydro is currently making plans for the development of Bipole III (BPIII), a 2300MW, +/-500kV HVdc Bipole that will run from Northern Manitoba to the Load centre in the south over a length of approximately 1300km. Both LCC and VSC ...
Limitations to loading the Manitoba Hydro future three-bipole, multi-egress, multi-infeed HVdc system and mitigation strategies
The Manitoba Hydro major transmission system features a topology consisting of very high HVdc penetration level, tightly coupled rectifiers as well as tightly coupled inverters. The tight coupling at the rectifiers or the sending end result...
Increasing the GB electricity transmission networks' power transfer capability between North and South — The Western HVDC Link
The paper highlights the main drivers for the Western Link HVDC project from the Transmission Owners' point of view, the main project milestones, the challenges as well as the proposed technical solution. On the technical side the focus is ...

IEE Colloquium on '50kV Autotransformer Traction Supply Systems - the French Experience' (Digest No.1993/209)
Why the 2*25 kV alternative? (autotransformer traction supply)
The author describes how it was the electrotechnical aspect in the form of reduction of losses on lines which was attractive in 2*25 kV traction power feeds in France; the first application was in 1981 on the new Paris-Lyon high speed railw...
SNCF relations with the power supplies
EDF, the public utility national grid in France, requires its customers to observe rules so that unacceptable phenomena will not be generated on the high voltage network, the aim being to provide power to its adjacent customers under good c...
The autotransformer and other equipment (for railway power supply)
The author describes the two types of equipment for 2*25 kV railway traction power supply installations: equipment specific to this alternative which is confined to substation transformers (high voltage or very high voltage/2*25 kV) and aut...
Earthing, protection, miscellaneous (of railway power systems)
The considerable increase in recent years of the per unit power of trains as well as their frequency has led the SNCF to take steps to simplify substation traction current return and to limit dangerous parasite voltages which might occur at...
