集群技术在电力综合自动化系统中的应用研究

介绍了一种利用集群技术实现双机容错的开发方法.通过对集群技术运行机制的深入研究,提出了采用基于"层"模式的双机容错系统技术方案,在普通PC服务器上实现了双机容错系统,分析了该系统的可用性,针对电力综合自动系统的结构特点,对心跳侦测等功能进行了改进,并在一套小型变电站自动化系统上进行了实验验证,能够较好的满足中小型电力综合自动化系统的需求.

Introduces the methods of the developing the fault tolerance system based on cluster.By studing the technology of cluster,the paper carried out a hot-redundancy system with common PC server which adopts a "layer"module,anilized the reliability of the system,and improved some of the functions such as Heartbeat Environment Adaptability,and it has been applied in a comprehensive automatic system for substation.
