Air Core Reactors for HVDC

HVDC lines are used for long-distance bulk power transmission up to 1100kV as well as back-to-back interconnections between different transmission networks. HVDC schemes are increasingly used also for grid connection of modern renewable energy facilites (e.g. offshore wind farms).

Trench has been the first supplier worldwide supplying smoothing reactors in air-core technology in the early 1980s. This breaktrough technology is today used in almost all new HVDC projects. The Trench portfolio for HVDC applications includes:

  • Smooting reactors
  • AC and DC Harmonic Filter Reactors
  • AC and DC PLC Noise Filter Reactors
  • Converter Reactors for VSC HVDC

Reactors for HVDC converter stations represent a vital element in the AC/DC power circuits.

Main Features

HVDC Reactors have been used in HVDC transmission lines for system voltages up to 800 kV. They normally include Smoothing Reactors, AC and DC Harmonic Filter Reactors as well as AC and DC PLC Noise Filter Reactors.

Smoothing Reactors are used to reduce the magnitude of the ripple current in a DC system.

HVDC systems with line commutated converters normally include:

SMOOTHING REACTORS
which are used to reduce the magnitude of the ripple current in the HVDC system

AC AND DC HARMONIC FILTER REACTORS

AC AND DC PLC NOISE FILTER REACTORS
Self-commutated HVDC (VSC) schemes usually include converter reactors and smoothing reactors (depending on the HVDC scheme)
