Design of Sand-Prevention Measures for ±800 kV UHV Converter Station

doi:10.11930/j.issn.10.11930.2015.11.76

Abstract

Abstract: For the converter station located in a sandy area, the dust will cause harmful impact on electrical equipment, buildings and structures in the station, and even threaten the safe operation of the station. Along with a large number of UHV DC projects planned in the sandstorm-prone areas in northwest China, it is thus imperative to carry out an in-depth study on the sand-prevention measures for the converter stations to ensure their successful construction and operation. Based on an investigation on the design and operation situation of the existing converter stations in sandy area, a summary and analysis is made on the specific sand-prevention measures for the electrical equipment, buildings and structures of the convertor station, which cab provide a technical support and reference to the design of the sand-prevention measures for the future power transformation projects, especially the UHV DC converter stations in the sandy area.

Key words: sandstorm-prone environment, UHVDC, converter station, sand and dust, preventive measurement
