摘　　要：为提高智能电网调度控制系统前置通信的可靠性与数据通道的冗余度,采用双远动装置分别接入双平面的调度数据网,即采用主备通道进行信息传输,这样就存在调控主站多通道接收的值及接收的频度不尽相同的可能。提出了一种智能电网调度控制系统多通道信息智能比对方法,通过网络监听方式获取主厂站信息交互通信报文,利用智能比对算法对遥信、遥测、事件顺序记录(sequence of event,SOE)、遥控、遥调等通信规约参数进行比对,根据比对结果及时输出告警事件。智能电网调度控制系统多通道信息智能比对技术是实现主厂站通道通信质量监测的有效手段,通过该技术可及时发现通道的异常,大大提高了调度自动化系统运行的效率。In order to improve the data communication reliability and the data channel redundancy of smart grid power dispatching automation system, the main ＆ spare channel for gathering and transmitting information is applied in the today＇s power system, which consequently leads to asynchronous between dispatching automation system and receiving frequency. A new method is presented in this paper, which can intelligently match the power dispatching automation system with the main ＆ spare channel information. The interactive communication message between power dispatching automation system and substation is obtained through network monitoring. The intelligent alignment algorithm is used to compare such communication protocol parameters as remote state, telemetry, SOE, remote control and remote adjustment, and the alarm event is outputted timely according to the compared result. The proposed method is effective in monitoring the quality of main ＆ spare channel communication and detecting the channel abnormalities, and carl greatly improve the efficiency of the dispatching automation system.
