摘　　要：介绍五凌集控监控系统集群通信现状和特点,根据生产实际需要分析了其中不足之处,提出了优化升级方案,进行一系列功能优化,实现集群通信通道手动切换、物理通道硬件监视、主从站时间偏差监视和从站一键屏蔽上送等功能;扩展了104规约,实现自动核对主从站信息、字符串信息上送集控、电站命令返送集控及计划曲线上送和下发功能。此方法可针对中大型水电和新能源电站集中监控系统通用需求,有效解决同类中大型数据网集群通信存在的问题。This paper introduces the status and characteristics of cluster communication in Wuling Centralized Control Monitoring System,analyzes its shortcomings according to the actual production needs,suggests an upgrading scheme and carries out a series of functional optimizations,presents how itrealizes the functions of cluster communication channel manual switching,physical channel hardware monitoring,master-slave time deviation monitoring and slave one key shielding upload,etc.In addition,this paper extends 104 protocol and realizes the functions of automatic verification of master-slave station information,string information uploading to centralized control,power station command returning to centralized control,and plan curve uploading and sending.The method could meet the general requirements of centralized monitoring system for medium and large hydropower stations and new energy power stations,and effectively solve the problems of cluster communication in similar medium and large data networks.
