ABB 101300 -±800kV ABB VCU Valve Control Unit Summary of Interface Between Pole Control System and Valve Control in JPS800 Project Zhang Hong Fan Jianzhong Liu Zhiyang (ABB Sifang Power System Co., Ltd, Beijing 101300) Abstract Jinping-Sunan ±800kV Ultra High Voltage Direct Current(UHVDC) transmission project presents the highest level of HVDC transmission technology in the world today. The reasonable design of Interface between pole control system and valve control system is a key part that ensure the project operates safely, stably and efficiently. Take VCU(Valve Control Unit) of ABB company for example, the design principles of interface between pole control system and valve control system are elaborated in the paper. Treatment scheme of interface between pole control system and valve control system in detail is put forward according to the requirement of valve manufacturers. Factory System Test(FST), commissioning test in site and successful operation in Jinsu project verify the correctness of design principle and scheme about the interface of pole control system and valve control system in the paper.
