Layout, Area, and Building Volume Requirements for HV DC Terminals

The different solutions for equipment layouts that are available in the construction of terminals for HV dc transmissions are introduced and discussed. Land area and the building volume requirements for the different layouts have been developed. These figures can be used as a base for system planning consideration and preliminary terminal cost estimates. Cost for premises and of building construction of the terminal buildings are also discussed. It is shown that the variation in this respect is considerable from location to location so that the most suitable layout will vary from case to case. Four alternative layouts are introduced. From the figures of these it is possible to select the type of layout which should be applied in a specific case.
