Abstract

Abstract: Converter valve is the core equipment of UHVDC transmission projects, and the valve control system and its interface play an important part in the reliability of UHVDC system. According to the valve control theory, a study is made in this paper on the general interface technology of valve control system in UHVDC project on the basis of a summary of the valve control system characteristics of existing UHVDC projects. The paper introduces the general interface technical scheme of valve control system in terms of overall principle, interface signals configuration and logical processing. The rationality is illustrated by real-time digital simulation test. The results are helpful for promoting the standardized design of valve control system in UHVDC projects and improving UHVDC operation reliability.

Key words: UHVDC, converter valve control, HVDC control and protection system, general interface
