基于OPC的远动机转发表组态数据自动提取及比对方法

Automatic Extraction and Comparison Method of Configuration Data of Telecontrol Forwarding Table Based on OPC

目前,在电力企业中,在变电站远动机转发表组态更改过程中存在误修改或漏修改风险,并且变电站远动机通常采用双机冗余配置,使得工作量进一步加大,采用人工方式对两个转发表进行核对不仅繁琐耗时而且容易出现误差。通过软件实现自动比对,可以提高工作效率和核对准确率,降低电网监控信息误报风险,避免通道转发表存在误修改或不一致问题引发的自动化事故事件,保证电力监控系统的安全性。

At present,in electric power enterprises,there is a risk of wrong modification or missing modification in the configuration change of substation telecontrol forwarding table.Moreover,the substation remote machine usually adopts double machine redundant configuration,which further increases the workload.Using manual method to check the two forwarding tables is not only cumbersome and time-consuming,but also prone to errors.Automatic comparison through software can improve work efficiency and check accuracy,reduce the risk of false alarm of power grid monitoring information,avoid automatic accidents caused by incorrect modification or inconsistency of channel forwarding table,and ensure the safety of power monitoring system.
