Ofgem· PDF filewere considered separately. An HVDC interconnector will comprise two converters, hence the unavailability for a single converter was assumed to be 0.325%. Two further reports on HVDC reliability have been published by B4-04 since the SKM model was created6,7. The CIGRE paper B4-1317 is the first to report on the reliability of VSC systems,
What is an HVDC (High Voltage Direct Current) Transmission ... HVDC converter transformer can be built as three-phase units or as single-phase units depending on voltage and power rating. When built as three-phase transformers there is generally one unit with the valve winding arranged for star connection and the other unit for delta connection. In single-phase design, the two valve windings are generally built on the same transformer unit.
Switchgear - Wikipedia an electric power system, switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream. This type of equipment is directly linked to the reliability of the electricity supply.
