Research on the Selection of Key Electrical Equipments in Offshore VSC-HVDC Converter Station

Abstract

[Introduction] For offshore VSC-HVDC converter stations, the environmental conditions are harsh and the construction is difficult. The selection of the main equipment has a great influence on the overall layout of the converter station. Reasonable selection of the key equipment will increase the reliability of the converter station and reduce construction costs, reducing maintenance work and the overall cost of the project. [Method] Analysing the composition of key equipment of the main circuit and the operational characteristics of offshore VSC-HVDC converter station. [Result] By focusing on the analysis of the type selection scheme and basis, we demonstrate the principle of equipment selection for offshore VSC-HVDC converter station. [Conclusion] The research conclusions is instructive and provide important design and application basis for the offshore converter station project.
