摘　　要：如何增强调度系统的可靠性,一直是电力行业内的重点研究内容。Harris 20-20容灾调度系统采用双机冗余热备份的方式,将调度系统设置为主、备2套系统,只要任意一套维持正常工作,即可保证调度通信不中断,增强了调度系统的可靠性。文章主要介绍了Harris 20-20容灾调度系统的基本构成及实现原理,并通过理论计算证明其有效性,还列举了一个容灾调度工程实例,供同行们参考。Enhancing the reliability of dispatching system is a key point in power industry. The Harris 20-20 backup dispatching system adopts hot standby redundant mode which consists of an active system and a standby system. When any of the two systems works normally, the dispatching communication will be ensured, thus the reliability of the dispatching system is enhanced. This arti- cle mainly introduces the basic structure and the realization of Harris 20-20 backup dispatching system. Through theoretical calculation, the validity of the system has been proved. An example of backup dispatch system is also given for reference in the article.
