摘　　要：随着调度业务的增长,双机同组技术逐渐暴露出因通道带宽受限而存在消息拥塞或丢失的风险。为解决上述问题,文章提出了多机同组技术,即将2个及以上不同交换机的下属调度台定义在同一个调度组内,调度组内通过信息共享实现调度交换系统的多级冗余备份。同时,还对比了双机同组系统的技术异同点,从硬件架构、逻辑架构、功能协议等方面研究了多机同组技术的设计与实现原理,并对该项技术在国家电网电力调度系统的实际应用案例进行深入分析,展望了多机同组技术在电力调度生产业务中的应用,为公司电力业务的大融合提供可行的意见。With the increasing of dispatching service,the risk of message congestion or loss due to bandwidth limitation of dual-machine in one group has gradually exposed.In order to solve the problems,the technology of multiple dispatching machines in one group has been presented.Multiple dispatching mechanism of one group means to set several dispatching desks including two or more different dispatching machines in the same group,so as to realize information sharing within the group and multi-level redundant backup of the dispatching system.This paper analyzes its similarities and differences with dual-machine in one group,studies the design and implementation principle of multiple-machine in one dispatching group from the hardware architecture,logic architecture and functional protocol,and analyzes practical cases applied in power dispatching system of State Grid.By putting forward the application of multiple-machine in one group in power dispatching and production business,feasible suggestions for the integration of power business are provided.
