摘要
在工业电气自动化系统中,越来越多的传感器加入到了供配电系统之中,形成了智能化的供配电系统。针对智能配电系统的多种需求问题,并基于智能变电站监测方式不便,检测精度不高的问题,设计出一种基于交换机的智能变电站过程层监测系统。通过在监测组网中布局不同形式的交换机系统,能够实现智能变电站的多种方式检测,并且通过构建网络拓扑结构图,使得基于交换机的智能变电站组网系统更加显而易见。同时,基于故障关联性规则挖掘算法实现组网数据的故障计算,通过加权的Apriori关联规则算法对过程层网络拓扑结构的交换机应用情况进行关联性规则挖掘,通过确定组网系统中的每个网络的权重网络流量、装置连接情况、交换机CPU利用率等属性,进行网络警告等级的确定。通过试验表明,此监测系统精度较高,误差较小。
In the industrial electrical automation system, more and more sensors have been added to the power supply and distribution system which formed an intelligent power supply and distribution system. According to the multiple needs of the intelligent power distribution system, and the inconvenience of the smart substation monitoring method, as well as the problem of low detection accuracy, an intelligent substation process-level monitoring system based on switches is designed. By deploying different types of switch systems in the monitoring network, multiple ways of detecting intelligent substations can be achieved, and by building a network topology diagram, the switch-based intelligent substation networking system is made more visible. At the same time, based on the fault association rule mining algorithm, the fault calculation of the network data is realized. The weighted Apriori association rule algorithm is used to mine the association rules of the process layer network topology switch application. By determining each network in the networking system, the network warning level based on attributes such as network traffic, device connection, and switch CPU utilization is determined. The monitoring system is proved to have higher accuracy and smaller error through the test.
