Abstract

The site object of this work connects Sellindge, England, and Les Mandarins by a National Grid and Réseau de Electricity Transmission Network, usually known as RTE, to allow the transfer of high-voltage electricity from England to France and vice versa. The aim of the project studied is the renovation of two converter stations having a capacity of 2 × 1000 MW high-voltage direct current (HVDC) with an electric potential of 270 KV, and the link connecting the Great Britain (GB) and French transmission systems was attributed to AREVA T&D (PC 8892 A AREVA, IFA 2000 Valves & Controls Replacement Project Sellindge and Les, 2009). After this, the electricity is produced at a power station, where it will be distributed to the customers.
This study concerns the building of the valve halls mandarins, France. The valves have to be replaced because the existing valves discharge all of their heat into the halls, whereas the new valves will have water cooling systems to remove most of the heat at source. However, some heat will still be discharged into the halls, so the ventilation systems must be changed to assure the requirements of the new valves and to maintain the halls at the suitable conditions.
The produced electricity is transferred towards the outside via the overhead conductors which operate at high voltage and connect the valves with the bushings. The maximum air temperature around bushings must be lower than 40 °C. The high degree of temperature is not supported by the bushings and will be damaged.
