Abstract:

Combined with the structure of the converter control and protection system in the flexible DC distribution network,the interface design scheme of voltage source converter (VSC) converter control and protection system suitable for flexible DC distribution network is presented.The functions of converter control and protection,valve control unit and power sub module are described,and the topology of half bridge power sub module is introduced in detail.The physical layer mode and specific communication content between each level are described,including the up-down communication content of converter control protection and valve control unit,the up-down communication content of valve control unit and power sub module central control board,and the sub module status information uploaded by the central control board is defined in detail.The research results provide reference for engineering application.

Key words: flexible DC distribution network, voltage source converter (VSC), converter control and protection (CCP), vavle control unit, central control board
