Since the commissioning of the 2,000MW DC link in the 1980s, the bulk of power flow through the link has been from France to Britain. 0000094349 00000 n Indeed, by 1984 the circuit was disconnected from the Main Transmission System. The landside parts of the link consist of 8cables with lengths of 18.5km (11.5miles) in England, and 6.35km (03.95miles) in France.[7]. Line Commutated Converters Line Commutated Converter is a mature cost effective HVDC technology based on thyristor power semiconductors, which enables the bulk transfer of power of up to 8 GW with low losses and inherent DC fault protection. A concept thunder (or your spark gap) has learned long ago. IFA is the European link combining the technical and commercial expertise of both RTE and National Grid Interconnectors. The Sellindge converter station was built by GEC and the Les Mandarins converter station was built by CGE Alstom. The undersea section consists of eight 46km (29miles) . 1 The Sellindge Converter Station is the UK terminal for the France Interconnector. National Grid said that it had been able to reduce that outage time slightly, meaning that it will come back to service on October 20 rather than October 23. The British landing point for the subsea cables is near Folkestone, Kent, from where underground cables connect to Sellindge converter station and then on to the UK transmission system. The system was built with solid-state semiconductor thyristor valves from the outset. 0000030179 00000 n Work is making visible leaps forward with the framework for the valve hall and control building now standing tall. This is done by means of high-power, high-voltage electronic semiconductor valves. You are either using a browser that does not support JavaScript, or you have disabled JavaScript.

Whilst repairs were undertaken there was considerable down time on the circuit resulting in a loss of trading. This latest project aims to support the extension of the operational life of the converter station through a refurbishment programme, with a focus on ensuring interoperability of legacy and the latest control systems. Improve quality, stability and maximize network performance. Although each station includes an earth electrode, this is used only to provide a neutral reference, and only one of the two electrodes is connected at a given time so that there can be no current flow between them. A fire at National Grid's IFA1 interconnector site in Sellindge is to see power prices once again spike in the UK as 1GW of capacity drops off the system. The maximum transmission power of this cable was 160megawatts (MW). This does get around the limited direct links between Belgium and France. The HVDC Cross-Channel (French: Interconnexion France Angleterre) is the name given to two different high-voltage direct current (HVDC) interconnectors that operate or have operated under the English Channel between the continental European and British electricity grids.. 3.
