Definitions

  • the present invention relates to high voltage direct current (HVDC) cables and to subsea installation of such cables.
  • HVDC high voltage direct current
  • Such cables and installations are described in WO 97/04466 (G Balog 13).
  • UK 2 295 506 describes a HVDC system in which rectifier and convertors are connected by a DC link, the inverter extinction angle is used to control the rectifier firing angle in a closed loop to maintain the inverter extinction angle at or above predetermined values.
  • Each converter has a closed loop controller to control the firing angle in dependence upon DC current, DC voltage, own extinction angle and own firing angle.
  • DE 1 262 425 relates to a device for 'voltagewise relief' of cables in HVDC installations where both ends are connected to an AC network via 'smoothing' coils and rectifiers, - and where the feeding and the receiving AC network as well as the associated rectifier are such that the number of phases on the two AC sides do not contain the same prime numbers.
  • a normal way to transfer energy from one place to another across a body of water such as between Norway and Denmark, - is to use a HVDC cable having a central insulated conductor and use the seawater for the return current. This cable is installed between AC circuits having the same number of phases.
  • An alternative is to install a separate HVDC cable for the return current in parallel with the first cable. This is an expensive solution.
  • the object of the invention is to provide a new cable and a new installation technique in order to satisfy customers requirements for reliable long distance transfer of high energy between to locations which are separated by a body of water, - at a reasonable cost.
  • the cable crossection shows a central cable conductor having one or more layers of insulation material 2 enclosed within a metal sheath.
  • Inner and outer semiconductive layers arranged respectively over the cable conductor 1 and underneath the lead sheath 3 are not shown.
  • Over the lead sheath there are successively arranged an insulation sheath 4, reinforcements 5, armour 6, insulation 7, armour 8 and outer protective layers 9.
  • the conductor 1 may be a multiwire copper conductor.
  • the insulation 2 may be wrapped tapes or extruded insulation.
  • the metal sheath 2 may be a conventional lead alloy sheath.
  • the first layer 4 over the metal sheath may be a polymer such as polyethylene (PE). This layer may be semiconductive in order to avoid or reduce potential differences.
  • Transversal reinforcements 5 such as stainless steel tapes are arranged over the layer 5.
  • a two layer armour 6 which may be hard-drawn profiled copper wires.
  • an insulation sheath 7 which may be a PE sheath
  • an armour 8 which may consist of galvanized steel wires and outer protection 9 which may consist of polypropylene yarn and asphalt.
  • the central conductor should have a crossection of 1.600 mm2 and the return conductor some 1.900 mm2 .
  • the cable should preferably be buried in the sea bed, preferably down to 2.5m depth.
  • FIG 2 is schematically indicated the main parts (conductor 1, return conductor 6 and armour 8) installed between two end stations A and B.
  • the stations A and B include convertors (not shown) for interconnection with AC networks (not shown).
  • the conductor 1 transfers the cable current from A to B and the armour 8 is earthed continuously.
  • the concentrical return conductor 6 is connected to ground potential through surge arrestors (valves)10 and 11 installed in both ends of the cable, - and the return conductor is earthed midway between A and B. This earthing may be achieved with semiconductive material.
  • the earthing of metallic return conductor must be done in such a way that no circulating currents will exist. At the same time the converters must experience the true earth.
  • the circulating currents are divided according to the resistances in the different loops. As the sea can be regarded as a very large conductor, only the resistance in the leads to the electrodes, the electrode resistance and eventual resistance in earth defines the loop resistances.
  • a cable with a metallic return conductor will at 800 MW load experience approximately 10 kV DC voltage buildup at a 540 km length. It is possible to use resistors to limit the earth current, but it is undesireable with any earth current. Another approach is to hinder the circulating current by singlepoint bonding. If direct earthing of one of the valves are necessary this may be possible; but the other valve group at the other end would experience 10 kV to earth.
