摘　　要：结合特高压直流输电工程的主回路接线特点,分析了特高压直流控制保护系统与常规直流的不同之处以及特殊要求,并对控制保护系统的整体结构、控制策略、分层及冗余、控制功能的分配及保护配置等进行了全面分析和研究,提出了可能的特高压直流控制保护系统的整体方案。According to the features of main circuit diagram of UHVDC project, the differences between the control and protection system for UHVDC project and conventional HVDC project as well as the special requirements of UHVDC project are analysed. All-round analysis and research on the control and protection system, i.e., the integral structure, control strategy, hierarchy of the structure and redundancy, distribution of control functions and configuration of the protection, etc., are carded out. Then a possible integral scheme of control and protection system for UHVDC project is put forward.
