基于无线网络的智能变电站监控信息自动核对新方法

A novel method for automatic verification of the monitoring information of smart substation based on wireless network

变电站是电网能源转换和运行控制的核心节点,当前数字化、标准化的智能变电站已广泛建设,数据通信网关机信息点表是变电站与主站信息交互的基础和关键。新建变电站时需要站端与调度主站逐条人工比对信息正确性,数以千计的信息点使得工作效率极其低下。提出变电站监控信息自动核对新方法,以智能变电站全站配置文件(SCD)和远动信息配置文件(RCD)为基础,利用无线网络通信技术,搭建系统实现新建变电站监控信息的自动核对,为新建变电站信息点表核对提供了新的有效手段。

Substation is the core node of power grid in energy conversion and operation control.At present,the digital and standardized smart substation has been widely constructed.The information table of data communication gateway is the foundation and key of interaction between substation and master station in dispatch center.When building a new substation,it is necessary to manually compare the correctness information between the station and the dispatching master station one by one.Usually,the remote information table of a new-built substation contains several thousands of points,which makes the working efficiency extremely low.To solve this problem,a novel method for automatic verification of the monitoring information is proposed in this paper.Based on SCD and RCD of smart substation,this method uses wireless technology to build a communication channel to realize the automatic checking of monitoring information in newly built substations,which provides a novel effective means for verifying the information of new-built substation.
