About the session

ACDC 2017 - The 13th IET international conference on AC and DC Power Transmission

Full presentation title - Fault arc extinction and system re-start on HVDC transmission lines using LCC or VSC full-bridge converters with integrated arc recovery simulation models

Session A3: DC Network Protection 2
Room: Alexandra B
Session chair: Norman MacLeod, Parsons Brinckerhoff, UK

This video covers:

LCC HVDC and VSC HVDC full-bridge converters are particularly suitable for the task of clearing fault arcs on HVDC transmission lines: they allow

  the extraction of energy stores in the power line

  the minimization of the energy fed into the fault

A dynamic recovery of the transmission line on the shortest possible timescale is made feasible if

  suitable re-start strategies

suitable arc recovery models, and

  suitable converter technologies are available.

We report on the development of a respective

  physical model of the arc and its extinction,

  the line recovery behaviour, and

  the implementation into a simulation tool of a bi-polar

  HVDC converter which inclusdes a transmission model.

This video covers the following topics: HVDC ransmission lines.
