Anhydrous Cooling Mode Applied in External cooling Equipment of HVDC Converter

Abstract

Anhydrous Cooling Mode is that it consumes little water in the operation process. This paper made some investigates in the external cooling equipment which is currently applied in the HVDC converter substation. There are some anhydrous cooling modes in the HVDC converter substation. A case of anhydrous cooling mode which air cooler series with the water chiller applied in the long distance natural gas pipeline pressurization was introduced. It is recommended that the cooling system composed of air cooler in series with chilling water will be preferentially chosen as an anhydrous cooling mode applied in the HVDC converter external cooling equipment.
