Abstract

Abstract:

Converter valve equipment is the core element in the secondary system of DC transmission, the interface device between converter valve and DC control system, as well as the important part in the control and protection of converter valve. Based on Hazheng project, the overall structures of UHVDC control system and converter valve control system were introduced in detail, as well as the interface mode and signal between DC control system and converter valve control system with different technical route. A perfect interface test program was designed in view of the diversity and complexity of valve control system in Hazheng project. Based on the interface test and problems encountered during the test, some optimized suggestions were proposed for the interface between DC control system and converter valve control system, which could reduce the complexity and facilitate the standardization of operation and maintenance of converter valve system in the follow-up projects .

Key words: UHVDC, DC control system, valve control system of converter valve, interface test
