摘　　要：提出了能完全满足《防止电力生产重大事故的二十五项重点要求继电保护实施细则》的双主双后双套的保护配置方案。从理论上分析了将主后备全套保护放置于同一硬件系统中不能构成独立运行的完整一套保护的原因。《反措实施细则》实际上将数字保护N-1的可靠性要求提高到N-2。同时指出,在同一套硬件系统中运行两套相同的保护实际等同于一个。该文为全面正确地执行《反措实施细则》提供了理论技术支持。A duplication mechanism for main and backup protections is presented,which completely satisfies《The25crucial required items of detailed regulations for preventing the serious events of power system》.Theoretical analysis points out that putting the main and backup protections in same hardware system is not a complete protective scheme operating independently.The objective of the Retailed Regulations is to upgrade the reliability of digital protection from N-1to N-2.Running two same sets of protection in same hardware system equals actually to one.The paper has offered theoretical and technical support for the complete and correct application of the Retailed Regulations.
