基于双机热备用的微机五防系统分层冗余策略

Research on Hierarchical Redundancy Strategy of Microcomputer Five-prevention System Based on Dual Hot Standby

为了提高变电站操作时微机五防系统的可靠性,提出了一种基于双机热备用的微机五防系统冗余策略。该策略将微机五防系统的通讯层面和应用层面进行拆分,分别实现不同功能下通讯层面的冗余策略和应用层面的冗余策略,能够有效提高微机五防系统的可靠性。

In order to improve the reliability of microcomputer five-prevention system in substation operation, this paper presents a redundancy strategy of microcomputer five-prevention system based on dual hot standby. In this strategy, the communication level and the application level of the microcomputer five-prevention system are separated, and the redundancy strategies of the communication level and the application level under different functions are realized respectively, which can effectively improve the reliability of the microcomputer five-prevention system.
