摘　　要：针对特高压直流工程的保护标准化需求,结合HCM5000平台的特点,提出一种适用于特高压直流工程保护系统的定值管理方案。制定基于以太网传输的定值报文通信规约,以图形化功能块方式实现多核CPU定值管理系统的主体功能,设计定值校核与文件保存机制,利用背板总线、MSI中断和共享内存等功能实现保护装置CPU间定值共享与保存。经测试,该定值管理方案可根据工程应用灵活配置,高效完成保护定值在线修改、查询、校核功能,有助于提升高压直流系统保护装置的标准化水平。According to the protection standardization requirements of UHVDC project,combined with the characteristics of HCM5000 platform,a setting value management scheme suitable for UHVDC project protection system is proposed.The communication protocol of protection value message based on Ethernet transmission is established,and the main function of the multi-core CPU setting value management system is realized in the way of graphical function block.The mechanism of setting value check and file saving is designed.The setting value sharing and saving between CPU of protection device is realized by using the functions of backplane bus,MSI interrupt and shared memory and so on.After testing,the setting value management scheme can be flexibly configured according to the engineering application,and can efficiently complete the online modification,query and check function,which will help to improve the standardization level of HVDC protection devices.
